U0607Lost Communication With Throttle/Pedal Position Sensor/Switch B
- Generic OBD-II code · Network
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Position sensor B is the redundant second track of a throttle or pedal unit. On SENT throttle bodies both tracks often share one sensor chip and even one frame (the dual throttle format A.1 of J2716), so a broken line usually drops A and B together. U0607 alone points to a fault confined to the second channel or its decoding. GM's 2025 tables (25OBDG03A) assign it to throttle position sensor 2 with the same SENT checks as sensor 1, Type A. On a GM engine with one throttle per bank (documents 23OBDG07 and 24OBDG07) it pairs with U0606 on bank 1 when the line stays silent or pulse or calibration lengths fall outside the window for 0.13 s. Ford's SENT summaries skip this code. With one track left, plausibility checks are gone, so power is limited.
- What you may notice
- Check engine light, on GM in the first trip
- Limited power because the redundancy check is lost
- Likely causes
- PossibleSecond sensor channel inside the throttle or pedal unit failed
- PossibleDamaged SENT line, supply or ground (often sets U0606 as well)
- PossibleSpread or corroded terminal at the sensor connector
- RareEngine controller software decoding the second channel wrongly
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Medium · Often possible to do yourself.Typical cost: €50 – €600
