N2 Input Speed Sensor Circuit
Symptom:N2 INPUT SPEED SENSOR CIRCUIT
When Monitored and Set Condition
When Monitored: Engine speed greater than 450 rpm, no engine speed DTCs, no TCM under-voltage system operation, no output speed sensor DTCs (signal from the ABS system), all wheel speeds above 250 rpm (signal from the ABS system), no rear wheel speed DTCs (signal from the ABS system), and no wheel slip detected (signal from the ABS system).
Set Condition: If the N2 input speed sensor is equal to 0 rpm or a short to ground, short to battery, open input speed sensor, faulty input speed sensor, open sensor supply circuit.
POSSIBLE CAUSES
- INTERMITTENT WIRING AND CONNECTORS
- SENSOR SUPPLY VOLTAGE CIRCUIT OPEN
- N2 INPUT SPEED SENSOR SIGNAL CIRCUIT OPEN
- N2 SPEED SENSOR SIGNAL CIRCUIT SHORT TO OTHER CIRCUIT
- SENSOR GROUND CIRCUIT OPEN
- SENSOR GROUND CIRCUIT SHORT TO OTHER CIRCUIT
- N2 INPUT SPEED SENSOR SIGNAL CIRCUIT SHORT TO GROUND
- SENSOR GROUND CIRCUIT SHORT TO GROUND
- N2 INPUT SPEED SENSOR
- TCM - N2 INPUT SPEED SENSOR
