Transmission Fluid Pressure Sensor Range/Performance Problem
The transmission fluid pressure sensor is giving readings outside the expected range.
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)
Your car's transmission fluid pressure sensor is not providing the right information, which can cause shifting problems or performance issues.
What the computer is actually seeing
The PCM looks for the pressure sensor's signal to be within a typical voltage range, usually around 0.5 to 4.5 volts. Anything outside that range triggers the code.
What a healthy reading looks like
Transmission fluid pressure should be between 40-90 psi at normal operating conditions. The sensor signal should read between 0.5-4.5 volts as the pressure varies.
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.
- 1Check the transmission fluid level; it should be within the proper range indicated on the dipstick.
- 2Inspect wiring and connectors for damage or corrosion, especially around the pressure sensor.
- 3Use a scan tool to check the live data from the transmission fluid pressure sensor; it should provide a voltage signal between 0.5 to 4.5 volts under changing conditions.
- 4If voltage readings are unstable or out of range, replace the transmission fluid pressure sensor and retest.
- 5If the sensor appears good, check for any mechanical issues within the transmission that could affect pressure. Include checking for blockages or faulty pumps.
Common causes
- Faulty transmission fluid pressure sensor
- Wiring issues or poor connections in the sensor circuit
- Low transmission fluid level
- Contaminated transmission fluid

Frequently asked questions
Is it safe to drive with this code?
It's not recommended to drive long distances as it can lead to serious transmission issues.
Will this code come back after clearing it?
If the root cause isn't fixed, the code will likely return after clearing.
Why does this code appear with other codes?
Transmission issues often have interrelated components, so multiple sensors can fail together.
