P1335

COMPONENT DESCRIPTION
The crankshaft position sensor (REF) is located on the oil pan (upper) facing the crankshaft pulley. It detects the TDC (Top Dead Center) signal (120 ° signal).
The sensor consists of a permanent magnet, core and coil. When engine is running, the gap between the sensor and the crankshaft pulley will periodically change. Permeability near the sensor also changes.
Due to the permeability change, the magnetic flux near the core is changed. Therefore, the voltage signal generated in the coil is changed.
The ECM receives the voltage signal and detects the TDC signal (120 ° signal).




CONSULT REFERENCE VALUE IN DATA MONITOR MODE
Specification data are reference values.




ECM TERMINALS AND REFERENCE VALUE
Specification data are reference values, and are measured between each terminal and (25) (ECM ground).




ON BOARD DIAGNOSIS LOGIC




FAIL-SAFE MODE
When the ECM enters the fail-safe mode, the MIL illuminates.

DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE
Perform "Procedure for malfunction A" first. If DTC cannot be confirmed, perform "Procedure for malfunction B and C".

Procedure malfunction A

NOTE: If "DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE" has been previously conducted, always turn ignition switch "OFF" and wait at least 10 seconds before conducting the next test.

TESTING CONDITION: Before performing the following procedure, confirm that battery voltage is more than 10.5 V.

With Consult
1. Turn ignition switch "ON" and select "DATA MONITOR" mode with CONSULT
2. Crank engine for at least 2 seconds.
3. If 1st trip DTC is detected, go to "DIAGNOSTIC PROCEDURE".

OR

With Generic Scan Tools
1. Crank engine for at least 2 seconds.
2. Select "MODE 7" with GST.
3. It 1st trip DTC is detected, go to "DIAGNOSTIC PROCEDURE".

OR

Without Scan Tools
1. Crank engine for at least 2 seconds.
2. Turn ignition switch "OFF", wait at least 10 seconds and then turn "ON".
3. Perform "Diagnostic Test Mode II (Self-diagnostic results)" with ECM.
4. If 1st trip DTC is detected, go to "DIAGNOSTIC PROCEDURE".




Procedure for malfunction B and C

NOTE: If "DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE" has been previously conducted, always turn ignition switch "OFF" and wait at least 10 seconds before conducting the next test.

TESTING CONDITION: Before performing the following procedure, confirm that battery voltage is more than 10.5 V at idle.

With Consult
1. Turn ignition switch "ON".
2. Select "DATA MONITOR" mode with CONSULT.
3. Start engine and run it for at least 2 seconds at idle speed.
4. If 1st trip DTC is detected, go to "DIAGNOSTIC PROCEDURE".

OR

With Generic Scan Tools
1. Start engine and run it for at least 2 seconds at idle speed.
2. Select "MODE 7" with GST
3. If 1st trip DTC is detected, go to "DIAGNOSTIC PROCEDURE".

OR

Without Scan Tools
1. Stan engine and run it for at least 2 seconds at idle speed.
2. Turn ignition switch "OFF", wait at least 10 seconds and then turn "ON".
3. Perform "Diagnostic Test Mode II" (Self-diagnostic results) with ECM.
4. If 1st trip DTC is detected, go to "DIAGNOSTIC PROCEDURE".

DIAGNOSTIC PROCEDURE





COMPONENT INSPECTION

Crankshaft position sensor (REF)
1. Disconnect crankshaft position sensor (REF) harness connector.
2. Loosen the fixing bolt of the sensor.
3. Remove the sensor.
4. Visually check the sensor for chipping.




5. Check resistance as shown in the image.
Resistance: Approximately 470 - 570 Ohm [At 20 °C (68 °F)]
6. If NG, replace crankshaft position sensor (REF).
