Description

DATA TROUBLE CODE: P1605

SYSTEM: Knock Control Central Processing Unit Malfunction

CIRCUIT DESCRIPTION
Knock Sensors are fitted one each to the right bank and left bank of the cylinder block to detect engine knocking. This sensor contains a piezoelectric element which generates a voltage when it becomes deformed, which occurs when the cylinder block vibrates due to knocking. If engine knocking occurs, ignition timing is retarded to suppress it.

DIAGNOSTIC TROUBLE CODE DETECTING CONDITION
- Engine control computer for knock control malfunction.

TROUBLE AREA
- Engine Control Module
