Fault Code 44
Notes: For 1985 - 1987 models only
temperature sensor voltage out of range
Power loss light: Off
Limp-in mode: Charging voltage set to 14V
Bad battery temperature sensor - This component is internal to the
power module. Verify the resistance of the sensor through the power
module's pin and ground. It should be about 10,000 ohms at 77^F.
If the component has failed, you can try to solder in a replacement, but
it is likely that the entire module must be replaced.
Bad connection or wiring - Check the wiring and connections to
the power module (or SMEC). Verify the sensor resistance at the logic
module (relative to ground) and that the line is being pulled up by the
module when the ignition is on (around 2.5V at 77^F).
- Sensor voltage is less than 0.04V or greater than 4.96V.
Results If Component Fails
Fault code 44 is stored and the charging rate is set to 14.0V. If
the sensor output comes back into range, the logic module will begin using
the sensor to calculate charging rates again.
