Symptoms
- Check engine light on
- Idle too high, too low or hunting
- Stalling when coming to a stop
- Speedometer or cruise control not working in some cases
Common causes
- Cruise Control Input Circuit worn, contaminated or out of calibration
- Mechanical problem in the system the sensor measures
- Air, vacuum or exhaust leak influencing the reading
- Wrong or low-quality replacement part
- Wiring resistance causing a small voltage offset
How to diagnose
- Compare the live Cruise Control Input Circuit reading with a known-good value or a second sensor at idle and at 2500 rpm
- Check for air, vacuum or exhaust leaks that could skew the reading
- Inspect the component for contamination and clean it if the design allows
- Verify the part number is correct for the engine
- Replace the Cruise Control Input Circuit if the reading remains out of specification
Frequently asked questions
Can I keep driving with P0575?
Usually yes for a short time, but expect reduced performance or higher fuel use. Have it diagnosed within a few days.
Will clearing P0575 fix it?
No. Clearing only erases the stored code; it returns as soon as the monitor runs again unless the cause is repaired.
