Rough idle: electronic EGR valve sticking inspection clues
Symptoms
- The engine idles roughly (rough idling) or hesitates during acceleration. [1]
Possible causes
- An EGR valve stuck by deposits or remaining open may cause these symptoms. [1]
Checks
- Check fault records, actuator tests and measured values; even when electrical operation is normal, check the valve for mechanical sticking. [1]
What to do
- When valve blockage is confirmed, first eliminate causes of increased contamination, such as engine oil entering the combustion chamber, then replace the faulty valve according to the model-specific requirements. [1]
Applicability and limits
- The measurement example is a 2002 Vauxhall Corsa C; do not use the example's pin assignments or resistance values as general specifications. No site brand/model dictionary mapping has yet been made; this cannot establish vehicle fitment. Scope: unknown [1]
