Transmission Range Switch Out of Range
The transmission range sensor is not in the expected range of operation.
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)
The computer is getting a signal from the transmission range sensor that doesn't match the gear you selected, like saying it's in 'Park' when it's actually in 'Drive'.
What the computer is actually seeing
The transmission control module expects the range switch to report the current gear position, like 0 volts in 'Park' to 5 volts in 'Drive'. If it reads outside this range (e.g., 2 volts in 'Drive'), it triggers a fault.
What a healthy reading looks like
Expected voltage range is 0V to 5V based on the transmission position, switching smoothly as you cycle through gears. Specifically, 'Park' should be near 0V and 'Drive' near 4-5V.
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. Visually inspect the wiring and connectors for damage or corrosion, especially at the transmission range sensor.
- 22. Check the transmission fluid level; if low, this could affect sensor operation. Fill to the recommended level if necessary.
- 33. Use a multimeter to measure the voltage at the transmission range sensor. Ensure voltage outputs match expected values at each gear position.
- 44. If voltages are out of expected range, check the wiring and connectors further up the harness for shorts or opens. Repair as needed.
- 55. If wiring is good, replace the transmission range sensor and recheck for proper operation.
Common causes
- Faulty transmission range sensor
- Wiring issues (shorts, opens) in the sensor circuit
- Corroded or damaged connectors
- Faulty transmission control module
- Improper installation or adjustment of the sensor

Frequently asked questions
Is it safe to drive with this code?
It's not recommended; the vehicle may unexpectedly shift or not shift, which could lead to loss of control.
Will this code come back after clearing?
Yes, if the underlying issue isn't fixed, the code will reappear shortly after clearing.
Why does this code pair with others?
Transmission codes can often be related; a faulty range sensor can cause or be caused by problems with other transmission components.
