U0761 Code:

OBD-II Diagnostic Network (U) Trouble Code

Possible Cause

The most common cause for this U0761 type of failure is due to liquids spilled on the upshift/downshift switch. Open or shorted electrical wiring, damaged, corroded, or disconnected wiring or connectors are also a viable possibility.

Common Symptoms

  1. Replacement of virtually all of these control modules will require reprogramming
  2. If the resistance level does not decrease with heat and increase as it cools, replace the sensor. If everything has checked out thus far, turn the key to the "ON" position and test for the presence of a voltage (and a ground signal) at the exhaust gas temperature/pressure (or heated oxygen) sensor electrical connector
  3. The PCM will read the sensor resistance and pass it
  4. If the fuel shutoff switch and all system circuitry checks out, suspect a defective PCM (or other related controller)

Refer to vehicle specific repair manual to perform component tests for the VCT unit.
