This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic.

The ECM turns the Check Engine Light on and goes into a failsafe mode by cutting current to the throttle actuator to put the throttle valve to approximately less than a 6 degrees opening. Note: The symptoms are determined by the manufacturer failsafe ECM strategy for the vehicle during a failure and may vary between manufacturers and vehicles.

Scans and documents the codes received, and views the freeze frame data to see when the code was set. Compares the data between TPS circuit A and B on the scanner and if incorrect, performs the TPS pinpoint tests as per the manufacturer's recommendations.

Not comparing the TPS sensor A and B to be within specification before and after repair or replacements. The P code will cause the engine's ECM to go into a failsafe mode, which will cause various drive issues like lack of acceleration, high idle, bucking or jerking, limited speeds, or stalling, depending on manufacturer failsafe mode strategy. The P code may be accompanied by other TPS codes, so following the manufacturer's pinpoint tests for each code received may be needed to fix the complaint.

It is relatively serious problem since it can leave your vehicle stranded or severely limited. Diagnosing it can be tricky without a good scanner and the knowledge of what you are doing. The symptoms of P are going to vary by year and model, but they certainly are going to cause noticeable changes in the way that your Yaris runs. Without a proper signal from the TPS, your vehicle will compensate in a number of ways. A good mechanic will utilize a scanner to diagnose when the codes were set and reset them.

If it all checks out and the code comes back, they may go ahead and replace the TPS sensor in question.

Most of the time, the problem when P is thrown will be the TPS sensor itself. It no longer is accurately tracking how hard the fuel pedal is being pushed. Diagnosing the issue with a scanner or having a mechanic take a look can save the expense of buying a TPS sensor that your Yaris does not actually need. Good luck diagnosing P in your Toyota Yaris.

There are factory service bulletins for the following Toyota models: Toyota Corolla Toyota Matrix The service bulletin recommends replacing the O2 sensors to fix the problem. The auto repair labor rates vary widely across the country, and even within the same city. If, after sufficient time has passed, the sensor still reports that the engine is not warm enough for closed-loop fuel control, the ECM interprets this as a fault in the sensor or cooling system and sets a Detected Trouble Code DTC.

After 5 minutes running time, the ECT sensor still indicates that the engine is not warm enough to begin active feedback control of the air-fuel ratio. The resistance of the sensor varies with the actual coolant temperature. The Engine Control Module ECM applies a voltage to the sensor and the varying resistance of the sensor causes the signal voltage to vary. Get Access to Factory Service Manuals.

Malfunction is detected when an excessively low or high voltage from the sensor is sent to ECM.

This sensor is a kind of potentiometer which transforms the throttle position into output voltage, and emits the voltage signal to the Engine Control Module ECM. In addition, the sensor detects the opening and closing speed of the throttle valve and feeds the voltage signal to the ECM.

Idle position of the throttle valve is determined by the ECM receiving the signal from the throttle position sensor. This sensor controls engine operation such as fuel cut. On the other hand, the Wide open and closed throttle position switch, which is built into the throttle position sensor unit, is not used for engine control. Get Access to Factory Service Manuals.

I am still having trouble with idle, it is high and it varies. Just before this code came up I was and am having a problem with high coolant temperature so I looked around at and moved some of the wires near the thermostat. Some of those wires go to the TPS. I might have a wiring problem of some kind….
