What does this fault code mean?
The ECM has logged an internal fault when comparing the signals from the narrow-range throttle position sensor. The fault may be caused by a poorly charged battery or corroded cables, but a damaged control module is also possible. If the fault is persistent, the engine control module needs replacing.
Possible causes
- Poorly charged battery
- Corroded connection cables
- Damaged engine control module (ECM)
What you can do
- 1Look at the battery terminals and cables for corrosion, and check that they are firmly seated
- 2Read and note the code, clear it and drive the car to see whether it returns
- 3If you have a diagnostic tool: read the diagnostic and fault status of the code and see whether it shows Malfunction found or No malfunction found
- 4If the fault remains after these checks: have a workshop check and, if needed, replace the engine control module
Symptoms you may notice3
- Rough idling
- Message in the information display
- Warning symbol and text message in the display
