cannot be identified at this time. If TP V PID voltage does not increase smoothly during throttle TEST DJ: AIR CONDITIONING EVAPORATOR TEMPERATURE SENSOR Diagnostic Aids Perform this test only when directed by QUICK TEST. This test is intended to diagnose the following: z Air Conditioning Evaporative Temperature (ACET) Sensor z Wiring Harness Circuits (ACET & SIG RTN) z Powertrain Control Module (PCM) DTC P1437 is set when ACET signal is more than self-test maximum of 4.5 volts. DTC P1436 is set when ACET SENSOR SPECIFICATIONS (1)
