SEVERECrankshaft Position Sensor A Circuit High Input
What this code means
Crankshaft Position Sensor A Circuit High Input. This is the most serious family of the set. A misfire sends unburnt fuel into the exhaust, where it destroys the catalytic converter within a few dozen kilometres. A flashing warning light means a misfire is happening now: stop driving.
How to read this code
- PPowertrain
- 0standardised code
- 3Ignition and misfire
- 38P0338
The letter P names the system: Powertrain. The digit 0 that follows marks a standardised code, shared by all manufacturers code. The next digit, 3, locates the fault: ignition and misfire.
What to do
Have it checked promptly. A misfire sends unburnt fuel into the exhaust and destroys the catalytic converter within a few dozen kilometres. If the light is flashing, stop driving.
Clearing a code switches the light off but repairs nothing: if the fault remains, the code comes back.
