What does code P1288 mean?

Q: What does code P1288 mean?

Cylinder Head Temperature Sensor Out of Self-Test Range. P1288 on Ford vehicles means the powertrain control module (PCM) ran its cylinder head temperature (CHT) sensor self-test and the signal fell outside the expected range for the current conditions. The PCM is not reporting a simple open or short circuit; it detected a plausible but out-of-range temperature reading during a key-on or running self-check.
