SEVEREThrottle/pedal Position Sensor/Switch B Circuit Range/Performance Problem
What this code means
Throttle/pedal Position Sensor/Switch B Circuit Range/Performance Problem. These codes point directly at the injectors and their electrical control. An injector that no longer sprays properly unbalances combustion in its cylinder, and usually brings misfire codes with it.
How to read this code
- PPowertrain
- 0standardised code
- 2Injector circuit
- 21P0221
The letter P names the system: Powertrain. The digit 0 that follows marks a standardised code, shared by all manufacturers code. The next digit, 2, locates the fault: injector circuit.
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.
