P2AB7Wastegate Position Sensor A Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2AB7 is the general circuit fault for the position sensor on wastegate A, found on engines whose wastegate is moved by an electric motor rather than a vacuum can. Turbo A is the first one in the exhaust flow on series layouts or the bank 1 unit on parallel layouts. Ford names P2AB7 in SSM 50485 for 2019-22 2.0L/2.3L EcoBoost models (Edge, Nautilus, Escape, Corsair, Bronco Sport), where a failed actuator, a lost e-clip or a bent rod led to a lack of power, and TSB 22-2357 cures false settings on 2021-22 F-150 2.7L trucks with new PCM software. Ford publishes no limit for this general code, only for the low and high variants P2AB8/P2AB9. GM reports a broken SENT link to the same sensor as U0644 instead. Bank 2 is P2ABA.
- What you may notice
- Check engine light on
- Noticeable lack of power, boost limited
- Often stored together with P0299 or the stuck wastegate codes P25B3/P25B4
- Likely causes
- LikelyElectric wastegate actuator failed, e-clip missing or actuator rod damaged (sensor sits in the actuator)
- PossibleChafed harness or loose connector near the hot turbocharger
- PossiblePCM calibration that sets the code falsely (reflash available for some models)
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
