Engine Disabling Sensor Failure
The engine disabling sensor has failed or is giving an incorrect reading.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
This sensor tells the engine computer if the engine should run or shut down; if it fails, the computer can't make that decision properly.
What the computer is actually seeing
The ECM is checking the signal from the engine disabling sensor. It expects a steady voltage around 5 volts when the sensor is good, and anything significantly below that may trigger the fault code.
What a healthy reading looks like
Voltage from the engine disabling sensor should read between 4.5V and 5.5V when active.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Check wiring and connector integrity at the engine disabling sensor. Repair any visible damage.
- 22. Measure the sensor output voltage with the engine running; it should be between 4.5V and 5.5V. If out of range, proceed to step 3.
- 33. Disconnect the engine disabling sensor and measure the resistance; check for an infinite reading (open circuit). If the resistance is low, replace the sensor.
- 44. If the sensor is good, test the wiring for shorts/opens back to the engine control module (ECM).
Common causes
- Wiring issues (frayed or shorted wires)
- Faulty engine disabling sensor
- Connector problems (corrosion or loose connections)
