Code No. P1965: Trustful Check Accelerator Pedal Position Sensor

FUNCTION

Compare accelerator pedal position sensor (main) output with accelerator pedal position sensor (sub) one.

TROUBLE JUDGMENT

Check Conditions

Ignition switch is "ON" position.
Monitoring time: per 25 ms.

Judgment Criteria

The difference between accelerator pedal position sensor (main) output value and the double of accelerator pedal position sensor (sub) output values is 1.0 V or more.
When the accelerator pedal position sensor (main) output voltage is constant, the change in the accelerator pedal position sensor (sub) output voltage is 0.03 V or more.

PROBABLE CAUSES

Failed accelerator pedal position sensor
Harness damage in accelerator pedal position sensor circuit
Failed engine-ECU or engine-A-M/T-ECU

DIAGNOSIS PROCEDURE

STEP 1. M.U.T.-III diagnosis code

Q. Diagnosis code set?

	Inspection chart for diagnosis code (Refer to ).

	Go to Step 2 .

STEP 2. M.U.T.-III data list

Refer to Data List Reference Table .

Item No. 11: Accelerator pedal position sensor (main)
Item No. 12: Accelerator pedal position sensor (sub)

Q. Are the check results normal?

	Replace the engine-ECU or engine-A-M/T-ECU then perform the variant coding (Refer to GROUP 00 - Precautions Before Service - How to Perform Variant Coding ).

	Perform the diagnosis code classified check procedure for the sensor that has shown an abnormal data value (Refer to Inspection Chart for Diagnosis Code ).
