Cost of diagnosing the P0537 code
Labor: 1.0The cost of diagnosing the P0537 code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected?When the A/C Evaporator Temperature (ACET) sensor signal is low the Powertrain Control Module (PCM) will triggered the P0537 code.
- Engine Light ON (or Service Engine Soon Warning Light)
- A/C Inoperative
- A/C Blows Warm
P0537 DescriptionThe Powertrain Control Module (PCM) sources a low current 5 volts on the A/C Evaporator Temperature (ACET) sensor circuit. As the A/C evaporator air temperature changes, the ACET circuit resistance changes (which changes the voltage the PCM detects).
