DTC B1422/22 Compressor Lock Sensor CircuitDESCRIPTION
DTC Detection Condition:
The ECM sends the engine speed signal to the TACO terminal of the A/C amplifier. The A/C amplifier reads the difference between compressor speed and engine speed. When the difference becomes too big, the A/C amplifier determines that the compressor locks, and turns the magnetic clutch off.
