P0325Knock Sensor 1 Circuit (Bank 1 or Single Sensor)
Voici ce que signifie le code défaut P0325, pourquoi il apparaît et que faire à son sujet.
Système: Ignition / knock control
Généralement sans danger sur de courtes distances, mais faites-le contrôler rapidement.
Ce que signifie P0325
The engine computer watches a knock sensor that listens for engine 'knock' (pinging) so it can adjust ignition timing. This code means the computer sees a problem in the knock sensor circuit on bank 1 (or the only sensor). With the sensor not working, the computer pulls timing back to protect the engine, which can hurt power and fuel economy.
Symptômes courants
- Check engine light on
- Reduced power or sluggish acceleration
- Slightly worse fuel economy
- Possible pinging or knocking noise under load
- Often no obvious symptom besides the light
Causes courantes
Classées de la plus courante à la moins courante.
- 1Faulty knock sensor
- 2Damaged, corroded, or loose wiring or connector at the sensor
- 3Open or short in the knock sensor circuit
- 4Poor ground or connector corrosion
- 5Engine mechanical knock causing real detonation
- 6Faulty engine control module (rare)
Que faire
It is usually safe to drive in the short term, but have it diagnosed soon because the engine may run with reduced timing and lost power. A shop will check the sensor and its wiring, and confirm there is no actual knock before replacing parts. On many engines the sensor sits under the intake, so labor can be significant.
