17 PCM Fault - Pull-Up Resistor

From SaturnWiki

[edit]

Description

The PCM uses a pull up resistor to increase resolution throughout the entire range of engine operating temperatures. When the coolant temperature is less than 40°C (104°F) the 4K ohm resistor is used. When temperature is above 40°C (104°F) the PCM switches to the 348 ohm resistor. If the pull up resistor does not switch, Code 17 will set.

[edit]

Code Parameters

Code 17 will set if:

  • The Pullup resistor inside the PCM switches and there is no change in the coolant temperatures signal.
[edit]

Diagnostic Aids

Code 17 is an internal fault within the PCM. The PCM must be replaced.
