DESCRIPTION
The accelerator pedal position sensor is mounted on the accelerator pedal bracket and has 2 sensors that detect the accelerator position and malfunctions of the accelerator pedal position sensor itself.
In the accelerator pedal position sensor, the voltage applied to pedal terminals PVS1 and PVS2 of the ECM changes between 0.2 V and 3.73 V in proportion to the opening angle of the accelerator pedal position sensor. The signal sent to PVS1 indicates the accelerator pedal opening angle, and PVS2 output is used for detecting a malfunction in the sensor.
The ECM determines the actual accelerator pedal angle with the signals transmitted from pedal terminals PVS1 and PVS2, and controls the engine based on these signals.
Tech Tips
The output voltage from PVS2 is half of that from PVS1.

INSPECTION PROCEDURE
Tech Tips
When DTC P0222, P0223, P0227 or P0228 is detected, check the accelerator pedal position sensor output voltage by selecting the following menu items on the intelligent tester: Powertrain / Engine and ECT / Data List / Accel Pos.
If only DTC P2137 is output, replace the accelerator pedal position sensor.
If only DTC P2299 is output, replace the accelerator pedal position sensor.
If the ECM is replaced, variant coding (variant coding indicates the presence of vehicle accessory items, A/C, etc.) should always be performed Click here.
Before removing the ECM and the peripheral parts, wait at least 3 minute after turning the ignition switch off (If the cooling fan is operating, remove the ECM and the peripheral parts after the fan stops.).
PROCEDURE
READ VALUE OF INTELLIGENT TESTER (ACCELERATOR PEDAL POSITION SENSOR VOLTAGE)
Connect the intelligent tester to the DLC3.
Turn the ignition switch to the ON position and turn the intelligent tester on.
Select the following menu items: Powertrain / Engine and ECT / Accel Pos.
Read the value.
