If the sensor input voltage is higher than the maximum threshold value under normal condition, the ECM/PCM sets DTC P0123.
Item | Detecting Condition | Possible Cause |
DTC Strategy |
•
Voltage Range check | 1. Poor connection 2. Short to power in signal circuit 3. TPS |
Enable Conditions |
•
Ignition key on
•
Engine operating state idle : Pedal value < 0.01% (pedal sensor 1 voltage 0.83 V, not pushed at all)
•
TPS setpoint < 58%
•
TPS 1 and TPS 2 ratio failure detected or TPS 2 failure detected | |
Threshold Value |
•
TPS_1 voltage > 4.9V
•
TPS_1 voltage at idle > 3V | |
Diagnostic Time |
•
Continuous. | |
Mil On Condition |
•
1 Driving cycles. |
