Possible DTC: P0120 (Accel position sensor 1)
Actual value for evaluation : Ignition on
Idle set value : 0%
Full throttle : 100%
＊ CC-CODE
C001 (Signal below the lower limit- No signal)
Possible causes of trouble :
Short circuit to GND line APS defective ECU defective (Sensor supply voltage): DTC P1526 C001 |
C002 (Signal above the upper limit)
Possible causes of trouble :
Short circuit to Bat line APS defective ECU defective (Sensor supply voltage): DTC P1526 C002 |
C003 (General error)
Possible causes of trouble :
Possible causes of trouble :
ECU defective (Sensor supply voltage): DTC P1526 |
C004 (Plausibility error with brake signal)
When depressing accel pedal (not at idle), brake switch signal is shown "ON" for a certain time, error is detected.
Possible causes of trouble :
Brake switch defective APS defective ECU defective (Sensor supply voltage); DTC P1526 |
Check the sensor supply voltage with ignition on.
Sensor 1: Pin 2(+) and pin 3(-), Sensor 2 : Pin 1 (+) and pin 5(-) (with APM)
Set value : 4.5 ~ 5.5V
Sensor 1: Pin 4(+) and pin 5(-), Sensor 2 : Pin 1 (+) and pin 6(-) (with APM)
Set value : 4.5 ~ 5.5V
If set value is not attained: Ignition off. ECU and sensor plug off. Check wiring for short or open circuit.
Check the following wiring.
With APS (XD/FO/SM-RHD)
ECU | APS 1 |
Pin 76 Pin 77 Pin 78 | Pin 5 Pin 2 Pin 4 |
With APM (LC/FC/SM-LHD)
ECU | APS 1 |
Pin 76 Pin 77 Pin 78 | Pin 5 Pin 2 Pin 4 |
If connecting leads are OK, measure the signal voltage of sensor.
With APM
- Sensor 1 :
Pin 4(+) and Pin 3(-) set value
At idle : 0.6 ~ 0.9V
At full throttle : 3.6 ~ 4.6V
With APS
- Sensor 1 :
Pin 2(+) and Pin 5(-) set value
At idle : 0.6 ~ 0.9V
At full throttle : 3.6 ~ 4.6V
