Electronic Ignition Timing Retard (1.8L)
Knock sensor is located at right rear of engine in cylinder block near water pump. Knock sensor sends a variable AC voltage signal to PCM depending on engine detonation. PCM uses this signal to determine if ignition timing should be retarded. If a fault occurs in knock sensor circuit or knock sensor fails, DTC P0325 can set in PCM memory. For test procedure with DTC set, see appropriate SELF-DIAGNOSTICS article.
