Sensors Codes

Crankshaft Position Sensor A Circuit Range/Performance

CKP sensor signal is outside expected range.

Crankshaft Position Sensor A Circuit Malfunction

The crankshaft position sensor (CKP) has a circuit fault. This sensor is essential for engine starting and timing.

Crankshaft Position Sensor A Circuit Low Input

CKP sensor signal voltage is too low.

Crankshaft Position Sensor A Circuit High Input

CKP sensor signal voltage is too high.

Power Steering Pressure Sensor Circuit Malfunction

The power steering pressure sensor circuit has an electrical fault.

Fuel Level Sensor A Circuit

Fault in the fuel level sensor circuit. The fuel gauge may read incorrectly.

Fuel Level Sensor A Circuit Range/Performance

The fuel level sensor reading is outside the expected range or not changing when it should.

Fuel Level Sensor A Circuit Low

The fuel level sensor signal is at minimum, possibly causing a false empty reading.

Fuel Level Sensor A Circuit High

The fuel level sensor signal is at maximum, causing a false full reading.

Vehicle Speed Sensor A Circuit Low

The VSS signal is at minimum or zero when vehicle speed is expected.

Vehicle Speed Sensor A Circuit High/Erratic

The VSS signal is erratic or reading higher than expected.

MAP Sensor Circuit Low Input

The ECM has detected that the Manifold Absolute Pressure (MAP) sensor signal voltage is lower than the expected operating range, which the ECM interprets as an implausible low-vacuum or low-pressure reading.

Power Steering Pressure Sensor Circuit Range/Performance

The power steering pressure sensor reading is outside expected range. This sensor tells the ECU when power steering load is high so idle speed can be increased.

Power Steering Pressure Sensor Circuit Low

The power steering pressure sensor signal is below minimum expected value.

MAP Sensor Circuit High Input

The ECM has detected that the Manifold Absolute Pressure (MAP) sensor signal voltage is higher than the expected operating range, causing the ECM to calculate an inaccurate engine load and richen the fuel mixture.

Vehicle Speed Sensor Malfunction

The ECM has detected no signal or an implausible signal from the Vehicle Speed Sensor (VSS), which is used for the speedometer, transmission shift scheduling, cruise control, and ABS.

Vehicle Speed Sensor A Range/Performance

The vehicle speed sensor is functioning but its readings are outside the expected range for current conditions.

Power Steering Pressure Sensor Circuit High

The power steering pressure sensor signal is above maximum expected value.
