Toysrme Posted August 25, 2006 Share Posted August 25, 2006 Knock sensor malfunction bank 1. 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. No No. 1 knock sensor signal to ECM for 4 crank revolutions with engine speed between 1,600 rpm - 5,200 rpm. Open or short in No. 1 knock sensor circuit No. 1 knock sensor (looseness) ECM If the ECM detects the above diagnosis conditions, it operates the fail safe function in which the corrective !Removed! angle value is set to the maximum value. That's what the FSM says. Download it. It's sticked at the top of the forum. DIAGNOSTIC CHART HINT: If diag. trouble code 52 is displayed, check No.2 knock sensor (for left bank) circuit. If diag. trouble code 55 is displayed, check No. 1 knock sensor (for right bank) circuit. If diag. trouble code 53 is displayed, replace ECM.
