P2C24Exhaust Heat Exchanger Exhaust Bypass Valve A Position Sensor Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P2C24 is stored when the position signal of exhaust heat exchanger bypass flap A drops below its permitted band. Typical reasons are a signal wire shorted to ground, an open sensor supply or an actuator whose sensor has failed low. CARB requires engine modules to check such inputs for readings outside their range and to keep separate codes for low, high and open where feasible. No manufacturer publishes P2C24 itself; Ford documents only the general circuit code P2C22 and the performance code P2C23 for the same sensor on its full hybrids, where SSM 53003 replaces the heat exchanger actuator on the F-150. An older Ford patent notes that such flaps often had no sensor at all, so the code only applies to actuators that report position. Warm-up may be slower; the MIL is expected.
- What you may notice
- Check engine light
- Heat recovery switched off, slower warm-up
- Likely causes
- LikelyPosition signal wire shorted to ground near the exhaust
- PossibleOpen or missing 5 V supply to the position sensor
- PossiblePosition sensor inside the actuator failed low
- RareWater in the actuator connector
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
