a. Install a normal engine speed sensor.
b. Connect engine speed sensor connector.
c. Turn ignition switch to ON, start the engine and observe the signal waveform of the engine speed sensor 

with an oscilloscope.

a. Turn crankshaft, and check crankshaft and flywheel gear ring for damage and foreign matter, etc. that 

cause signal incorrectness.

a. Use X-431 3G diagnostic tester to read the ECM DTC. 
b. Refer to "DTC Confirmation Procedure".
c. Check if DTC P0322-00 still exists.

Replace wire harness or connector 
(engine speed sensor - ECM)

DTC Confirmation Procedure

Confirm that battery voltage is over 12 V before performing the following procedures.
 Turn ignition switch to LOCK.
 Connect X-431 3G diagnostic tester (the latest software) to Data Link Connector (DLC).
 Turn ignition switch to ON.
 Use X-431 3G diagnostic tester to record and clear the DTCs stored in the ECM.
 Start the engine and warm it up to normal operating temperature, and then select Read Code.
 If the DTC is detected, the malfunction indicated by the DTC is current. Go to the diagnosis 

procedure - Step 1.

 If DTC is not detected, the malfunction indicated by the DTC is intermittent (

See page 06-18

).

Diagnosis Procedure

a. Turn ignition switch to LOCK.
b. Check ECM grounds E-026 and E-028 (

See page 06-18

). 

a. Disconnect knock sensor connector E-005.
b. Check knock sensor connector.
