TCM-0116

TCM-0116 Throttle Solenoid SLT
Signal Too High. Permanent Fault
Signal Too High. Intermittent Fault





Condition
Throttle solenoid SLT controls the line pressure in the transmission. The solenoid is controlled by a power stage in the Transmission Control Module (TCM) output. The Transmission Control Module (TCM) uses the power stage to control the current to the solenoid. A low amperage results in a high line pressure. A high amperage (approximately 1 A) gives a low line pressure. The amperage is primarily affected by the throttle position. Diagnostic Trouble Code (DTC) TCM-0116 is stored if the Transmission Control Module (TCM) registers a short-circuit to battery voltage in the solenoid SLT circuit. This results in too high an amperage. Solenoid SLT cannot then control the line pressure.

Substitute value
- The Transmission Control Module (TCM) "Emergency mode 1" program has been initiated.

Possible source
- Short-circuit to supply voltage in the control signal wiring or signal wiring.
- Short-circuit between the control signal cable and the signal cable.
- Defective solenoid.

Fault symptom[s]
- General orange warning lamp lit.
- No shifting.
- Malfunction Indicator Lamp (MIL) lit.
- No lock-up function.

Hint: No shifting because the control module prevents activation of the solenoids.

Caution! There is a danger that this fault will cause line pressure in the transmission to be too low. This will result in a high level of wear.
