Detonation Sensor

On 4-cylinder turbo models, the detonation sensor is mounted in the intake manifold in such a position so sensor can detect detonation in any cylinder. This sensor generates an input signal to SBEC when detonation occurs. The SBEC uses this input to adjust spark advance and boost schedules.

On 3.3L and 3.8L V6 models, detonation sensor is mounted on engine block where detonation in any cylinder can be detected by sensor. The SBEC uses this information to adjust spark advance.
