What Does C1136 Mean?
This code indicates the control module has detected that the gear select position sensor circuit is shorted to ground. The gear select sensor monitors the lateral position of the shifter in the gate, distinguishing between gear planes. A short to ground prevents the module from determining which gear plane the shifter is in.
Common Causes
35%
Damaged wiring in the shifter mechanism area where the harness is exposed to mechanical wear from shifter movement
25%
Failed gear select position sensor with internal short to ground
25%
Water or fluid intrusion at the sensor connector causing corrosion and short circuit to the connector shell
15%
Pinched wiring under the center console or at the transmission tunnel pass-through
Diagnostic Steps
1
Step 1: Disconnect the gear select sensor and verify if the code changes to an open circuit code. If so, the sensor is internally shorted to ground.
2
Step 2: With the sensor disconnected, check for short to ground on the signal wire by measuring resistance from the signal wire to chassis ground at the control module connector.
3
Step 3: Remove the shift boot and console trim to visually inspect the wiring around the shifter mechanism for wear, pinching, or fluid contamination.
4
Step 4: Test the sensor by measuring resistance between the signal terminal and the sensor housing ground. Compare to manufacturer specifications.
5
Step 5: Repair or replace the failed component, clear codes, and verify correct gear select position readings in live data while moving the shifter through all gate positions.
