Fault Code 23-TBI
Notes: For throttle body injected (N/A) models only
body temperature sensor signal out of range
Power loss light: On
Limp-in mode: Throttle body temperature of 70^F is assumed
Throttle body temperature sensor failure - The sensor should measure
9,120 ohms to 10,880 ohms at 77^F. This sensor is located on the
side of the throttle body, below the throttle plate.
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 0.06V or greater than 4.98V
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 throttle body temperature of
