INSPECTION PROCEDURE

HINT

- DTCs P0327 and P0328 are for the bank 1 knock control sensor circuit.

- DTCs P0332 and P0333 are for the bank 2 knock control sensor circuit.

- Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame

data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or

stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the

malfunction occurred.

PROCEDURE

1. INSPECT ECM (KNK1, KNK2 VOLTAGE)

(a) Disconnect the knock control sensor connector.

(b) Turn the engine switch on (IG).

(c) Measure the voltage according to the value(s) in the table below.
