Transmission Fluid Pressure Sensor

Indicates a problem with the transmission fluid pressure sensor.

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 uses a sensor to measure how much pressure is in the transmission fluid. If the pressure readings are too low or too high, it triggers a fault code.

What the computer is actually seeing

The transmission control module monitors input from the fluid pressure sensor to determine if the pressure is within expected limits. A reading outside the threshold activates the fault code.

What a healthy reading looks like

Normal fluid pressure should be between 20-100 PSI depending on engine load and transmission type.

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.

  1. 1Check for basic issues: Is the transmission fluid level correct?
  2. 2Inspect wiring and connectors to the transmission fluid pressure sensor for damage or corrosion.
  3. 3Using a scan tool, check live data for the fluid pressure sensor reading.
  4. 4If the reading is outside expected values (20-100 PSI), replace the sensor.
  5. 5If the reading is normal after replacing the sensor, further investigate the transmission for internal issues.

Common causes

  • Faulty transmission fluid pressure sensor
  • Wiring issue to the sensor
  • Low transmission fluid level
  • Internal transmission problems

Is it safe to drive with this code?

No, it's high severity; you may lose transmission function.

Will this code come back after fixing?

If the underlying issue is resolved, it should not return.

Why is this code related to SPN 1006?

SPN 1006 is a related fault indicating another aspect of transmission issues.
