About P1222

P1222 is a manufacturer-specific powertrain diagnostic trouble code recorded for Ford vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P1222 is stored, the module has detected a signal or supply voltage lower than the expected operating range; and a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

P1222 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

This Ford code has two applications depending on the vehicle. On systems using it for the accelerator pedal, DTC P1222 indicates the Accelerator Pedal Position (APP) sensor B signal has gone below its normal range, a low input, where sensor B is one of the redundant pedal signals the Powertrain Control Module (PCM) uses to confirm driver demand. On systems using it for traction control, the same code refers to a fault in the traction control output circuit that the PCM drives to signal or actuate the traction control function. In the pedal case the usual causes are a short to ground, an open, ...
