Question about 1992 Oldsmobile 88
A/c compressor it's ok it is charge there is no leaks some told me the problem was with body control module thank you
Tips for a great answer:
The electronic brake control module (EBCM)
The powertrain control module (PCM)
The sensing and diagnostic module (SDM)
You need a factory scan tool to diagnosis , it's the only way to see if transmission is sent an received !
The intake air temperature (IAT) sensor is a thermistor which measures the temperature of the air entering the engine. The Powertrain Control Module (PCM) applies 5.0 volts through a pull up resistor. When the intake air is cold, the sensor resistance is high and the PCM will monitor a high signal voltage on the IAT sensor signal circuit. As the intake air warm, the sensor resistance becomes lower causing the PCM to monitor a lower voltage. If the PCM detects an excessively high IAT sensor signal voltage (low temperature indicated), DTC P0113 will set.
Test the signal circuit of the IAT sensor for a short to voltage. Refer to Wiring Repairs in Wiring Systems.
