What U0607 means
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.
U0607 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U0607
- Check engine light, on GM in the first trip
- Limited power because the redundancy check is lost
Common causes of U0607
- 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
- Less likelyEngine controller software decoding the second channel wrongly
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0607 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 07 | The exact fault in that area. |
What to do next
- Note U0607 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about U0607
What does U0607 mean?
U0607 means "Lost Communication With Throttle/Pedal Position Sensor/Switch B". Position sensor B is the redundant second track of a throttle or pedal unit. It is a generic code, so it means the same on every make.
Is it safe to drive with U0607?
Drive gently and only to a workshop. With U0607 the car can go into limp mode (reduced power) to protect itself.
Will U0607 fail an emissions test?
Yes, it can. U0607 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is U0607 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will U0607 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
