The computer has one of the management functions that is the voltage supply to the sensors.
The sensor supply votage 2 is fed to the APS 2 and RPS to be used to operate the sensors.
If the signal is above threshold value, the ECM judged this as a fault and DTC is set.
Item | Detecting Condition | Possible Cause |
DTC Strategy | ● Signal check, high | ● Short to battery in power circuit ● Faulty RPS or APS ● Faulty ECM |
Enable Conditions | ● Ignition on | |
Threshold Value | ● Output signal > 5.15 V | |
Diagnostic Time | ● 0.1 sec. | |
MIL Fuel Limit Fuel Cut EGR Off | ● No ● Yes ● No ● No | |
Fail safe | ● Engine speed is fixed as 1200 rpm without the accel position sensor action. |
Sensor supply voltage 1 | |
Voltage | 4.8 ~ 5.1V |
