What it means
Throttle/pedal position sensor E does not reach the calibrated maximum-stop value during the wide-open self-test. Sensor wear, mechanical stop misalignment, or a stuck pedal.
At a glance
- Usually lights the check-engine light
- Affects emissions; the car can fail an emissions test
How it works
Throttle/pedal position sensor E tracks one of the electronic throttle system's position signals. The control module checks sensor E against its calibrated full-travel endpoint during a wide-open self-test; this code sets when sensor E does not reach that maximum.
Common causes
Most likely first.
- Throttle or pedal position sensor E worn or faulty
- Throttle or pedal mechanism not reaching its calibrated stop
- Binding throttle or pedal linkage
- Damaged wiring or connector
Symptoms
- Check engine light on
- Reduced throttle response, possible limp mode
- Hesitation or surging
- Idle too high or too low
How to diagnose it
- Save freeze-frame data and watch live sensor E alongside the other position signals while slowly pressing the pedal to identify whether E alone misses its endpoint.
- With the engine off, check for a mat, obstruction, or binding in the pedal or throttle mechanism that prevents full travel.
- Inspect the sensor E connector and wiring for loose or backed-out terminals, corrosion, or chafing.
- Test sensor E's signal, reference, and ground circuits while moving the pedal, comparing the readings with the manufacturer's specification.
- If full mechanical travel and wiring are confirmed, test sensor E or its integrated assembly using the manufacturer's procedure and carry out any specified relearn.
Common fixes
- Remove any obstruction or correct binding in the pedal or throttle mechanism.
- Repair the sensor E connector or harness fault.
- Replace the faulty sensor E or its integrated throttle or pedal assembly.
- Align the mechanical stop or perform the required relearn according to the manufacturer's procedure.
Can I keep driving?
If throttle response remains smooth and predictable, drive gently and avoid situations that need full acceleration. Do not continue if response surges or drops unexpectedly; limited or erratic power can create a hazard in traffic.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
