This code indicates that the throttle valve is not in the position the PCM Powertrain Control Module expects it to be in. Electronically controlled throttles found on most modern vehicles utilize PCM programming to set and monitor the throttle position.
Because of the complicated nature of programming, the PCM will often set codes for what it believes to be the problem. There are many scenarios where this code can be set but the problem is not in the ETCS components. It is important to recognize other symptoms and or codes that will indirectly set this code. The first step is to check for codes with a scanner and confirm the problem still exists. This is accomplished by clearing the code then test driving the vehicle.
Most of the time the problem will be apparent in the scan tool data. If the data is good but the code and or symptoms still persist, it will be necessary to test each component individually.

A visual inspection of the throttle plate operation should be first followed by pin-point tests at each component in the ECTS system. Pin-point tests will be outlined differently for each manufacturer and should be researched with a professional shop information system. A common mistake made is the failure to check if the throttle valve is actually moving. Internal components in the throttle body can break. Electrical connector issues are common on all vehicles and all systems.
Problem areas are not always visually apparent and warrant a more comprehensive look at the wiring harness and connectors of each component. It is easy to miss problems with connectors as these problems are not readily apparent to the eye. This code indicates a problem with the the throttle control system which is a vital system to the speed of any vehicle. If this system were without any failsafes, a failure in the system would pose significant danger to the occupants and any bystanders.
For this reason, if this code is set, the vehicle will usually lack a significant amount of power. Some manufacturers choose to put the vehicle into a shutdown mode for safety reasons.The engine will start but it wont rev up when I press on the gas pedal. Has a code P What is causing it how do I fix the problem? Do you. The code sets when battery voltage is low. Check all your fuses especially your ETCS fuse in the engine compartment. Also make sure battery is good and alternator is charging properly.
Here is a link to show you how to check the alternator. Image Click to enlarge. Was this answer. I check all the fuses they are good the alternator is charging what does code P mean? The ETCS fuses is not blown the alternator is charging the battery was low charge because I been cranking a lots I put a charge on the battery can the Throttle actuator control motor current range or performance be tested of the car?
You would need an advance scanner to check the throttle operation. Verify you have a battery power at the green wire at the throttle body.
If you have power then your throttle body has most likely failed. If the battery was dead make sure it is fully charge and reset the codes and recheck. Please login or register to post a reply. The power your car's engine is producing is important. When you step on the gas you need your car to accelerate, mainly to keep you out of trouble when getting onto the Asked by t6rivals hotmail.

In a fully functional throttle control system, a dedicated position sensor monitors the position of the throttle plate, and both this sensor and the accelerator pedal position sensor work in conjunction to verify the position of the throttle plate. Typically, though, one position sensor monitors the position and movement of the accelerator pedal, while another position sensor monitors the position of the throttle plate.
If the accelerator pedal is depressed or released in a fully functional system, the changing resistance in the pedal position sensor causes the PCM to either open or close the throttle plate by an amount that corresponds directly to the position of the accelerator pedal relative to a minimum stop position.
To improve overall performance of the throttle control system, the throttle control motor has its own dedicated and precisely controlled power supply circuit that is designed to work within very narrow parameters. When this happens, and depending on the application, throttle response may be severely limited or prevented altogether, and on some applications, it may not be possible to start the engine.
Moreover, regardless of the severity of the failsafe or limp mode, the application will remain in limp mode until the problem is resolved or corrected.
In this example, the actual DC motor is indicated by a red arrow, but note that although all motorized throttle control systems follow the same general principles of operation, the appearance, design, and layout of individual components relative to each other within the throttle body vary greatly between applications.
Note that on many, if not most applications the throttle control motor forms an integral part of the throttle body assembly, and cannot be replaced on its own.
In these cases, the entire throttle body assembly must be replaced as a compete unit. NOTE: Code P is often accompanied by other throttle control related codes, any one or more of which could have caused, or contributed to the setting of P Therefore, it is important to resolve additional codes in the exact order in which they were set and stored, since failure to do this could result in a misdiagnosis, and the unnecessary replacement of parts and components.

Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model to another. Vehicles with electronically controlled throttle bodies are equipped with a throttle actuator control motor, also known as drive-by-wire.
In this kind of system, the gas pedal acts as a sensor and sends a signal to the throttle actuator control motor, which then opens and closes the throttle place according to the demand.LEXUS RX350 P2118 wont accelerate ETCS also FUSE BOX LOCATION toyota rx
When the PCM powertrain control module, also known as ECM or engine control module has determined that the voltage is out of range, or there is the throttle actuator control motor is suffering from poor performance, it will set the Error Code P and simultaneously activate the Check Engine light. This Failsafe mode will be removed when the fault is resolved. Also, it can cause serious symptoms, such as vehicle not responding to gas pedal due to failsafe mode. Mechanics diagnose this code by using a scan tool to check for the codes stored in the PCM of the vehicle.
All the codes are noted, including the code history and pending codes. Each code will also have their freeze frame data associated with them; this tells the technician what the condition of the vehicle is at when the code was first stored.
All codes are then cleared, and the vehicle will be taken for a test drive. If after the test drive the code is still present, then the technician will proceed on its diagnosis. The technician will then conduct a visual inspection and look for obvious failed components or damages in the wiring.
The scan tool will be used to monitor the data stream and check both the throttle and gas position of the sensor values as they are operated.
A multimeter will then be used to check for voltage at the throttle actuator control motor. Lastly, the technician will remove the air intake and throttle body to inspect them and check whether the throttle plate is capable of moving. This error code is easy to repair, but of course, demands thorough diagnosis. Typical repairs include:.

Many people misdiagnose or make mistakes with this error code by simply overlooking the importance of thorough visual inspection. In many cases, repair is simply about finding the frayed wires and repairing them. It is crucial to follow all steps in their proper order and completed entirely before making repairs.
Because this code puts the vehicle in failsafe mode, it prevents the throttle from operating properly, which can lead to serious problems. The vehicle may not move or drive when the symptoms start to show up. Thus this code must be taken with extreme care, and the vehicle must not be driven until this problem is solved.P engine code seems a kind of powertrain problem, we try to show one by one the meaning and the solution.
Brief explanation of the P code and definition of P is the bottom side. MFG - Manufacturer Specific codes, which have a '1' as their second digit to indicate they are unique to a particular vehicle make or model. These special codes were deemed necessary by the vehicle manufacturers so they could provide additional diagnostic information beyond the basic list of generic OBD II codes for all kinds of faults, not just emissions-related faults.
Deactivation of cylinders is achieved by releasing a synchroniser pin that normally interlocks the cam follower and rocker arms. P code resolves the synchroniser pin is released using hydraulic pressure which is controlled by a dedicated solenoid. Is the fuel pump sometimes not priming when you turn the key to ON II? Start by measuring the fuel pressure and checking whether you have bright white-bluish spark at all four plugs.
The mechanical timing is also something that you should check, as we mentioned above. When you see P engine fault code on your engine code reader this description will help you. Final Step: In the definitions listed below, there is a test drive recommended after you've completed any repairs to see if the condition is fixed.
Before you take a test drive after a repair, always erase the P Code s first. This will turn the check engine light off and then you will know if the check engine light returns, you've got further diagnostics to complete. This engine code information is presented for information purposes only.
This is not intended as repair advice and we are not responsible for any actions you take on any vehicle. Example: P How To Fix P?Theoretically you can drive for a few weeks or even months with a broken MAF sensor. You will notice a decrease in gas mileage and over time the car will eventually start stalling a lot.
So you should chech it on our car models. The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time. If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver.
Parts or components should not be replaced with reference to only a P DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. Code Search Please fill the "Code Box" to find engine fault code.

Check engine light comes on Engine stalling or misfiring Engine performance issues Car not starting. If one of these reasons for P code is occuring now you should check P repair processes.
Now don't ask yourself; What should you do with P code? The solution is here :.Visually inspect the related wiring harness and connectors.
Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. When the power supply voltage drops below the threshold, the ECM concludes that the power supply circuit has an open circuit.
When the voltage becomes unstable, the ETCS itself becomes unstable. For this reason, when the voltage is low, the current to the actuator is cut. If repairs are made and the system has returned to normal, turn the ignition switch OFF. The ECM then allows current to flow to the actuator and actuator can be restarted.
