Fault Code 23-MPI-1984
Notes: For multi-port injected (turbo), 1984 models only
temperature sensor signal out of range
Power loss light: On
Limp-in mode: Charge temperature of 70^F is assumed
Charge temperature sensor failure - The sensor should measure 5,290
ohms to 5,610 ohms at 77^F. On 2.2L and 2.5L engines, this sensor
is located on the intake manifold.
Bad connection or wiring - Check the wiring and connections between
the sensor and the logic module (or SMEC). Clean and regrease any
corroded connectors with dielectric grease.
- Sensor output less than 0.157V or greater than 3.76V
Results If Component Fails
Fault code 23 is stored, the power loss light is turned on, and the logic
module will enter limp-in mode, assuming a charge temperature of 70^F.
