Fault codes covered
62-01
PEV (pressure equalization valve) is used to equalize pressures across the compressor prior to starting in order to ensure the compressor can align itself and start will minimal effort. The system will declare 62-01 when it senses the PEV coil is “open” or infinite resistance. The system will continue to operate while this fault is active as long as the pressures are within acceptable range prior to start attempt. If not, the system will not start until pressure differential drops to acceptable range.
Remove PEV connector from PCM and measure continuity between pins 1 & 3. If open, inspect wire for damage and repair if necessary. If no damage is found, replace coil and harness.
