P1437 2001 Ford F150 Code - A/C Evaporator Air Temperature Circuit High
Quick Answer
The A/C Evaporator Temperature (ACET) sensor contains a thermistor which receives a reference voltage from the Powertrain Control Module (PCM). Common causes include Faulty A/C Evaporator Temperature (ACET) Sensor, A/C Evaporator Temperature Sensor harness is open or shorted, A/C Evaporator Temperature Sensor circuit poor electrical connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.

Code P1437 2001 Ford F150 Description
The PCM maintains evaporator core temperature and prevents icing of the evaporator core, by disengaging the A/C compressor clutch when the evaporator A/C Evaporator Temperature sensor reading falls below acceptable levels, and by engaging the A/C compressor clutch when the discharge air temperature rises above acceptable levels.
The A/C Evaporator Temperature sensor is located inside of the heater core and evaporator core housing in the air-stream leaving the evaporator core.
The Diagnostic Trouble Code (DTC) indicates the A/C Evaporator Temperature sensor signal input is greater than Self-Test minimum. Self-Test maximum is 4.5 volts.
What are the Possible Causes of the DTC P1437 2001 Ford F150?
- Faulty A/C Evaporator Temperature (ACET) Sensor
- A/C Evaporator Temperature Sensor harness is open or shorted
- A/C Evaporator Temperature Sensor circuit poor electrical connection
- Faulty Powertrain Control Module (PCM)
How to Fix the DTC P1437 2001 Ford F150?
