M : DTC P0340

M1: CHECK THE CAMSHAFT POSITION SENSOR FOR CORRECT INSTALLATION

1. Switch the ignition switch to the OFF position.
2. Check the camshaft position sensor for correct installation

Is the camshaft position sensor correctly installed?

Yes

Go to M2

No
INSTALL the camshaft position sensor correctly. CLEAR DTC. TEST the system for normal operation.

M2: CHECK THE RESISTANCE OF THE CAMSHAFT POSITION SENSOR
1. Remove the plastic engine cover.
2. Disconnect the camshaft position sensor electrical connector PI11.
3. Measure the resistance between the camshaft position sensor electrical connector PI11 pin 1, (WB) and Pin 2, (NY).

Is the resistance between 200 and 400 ohms?

Yes

Go to M3

No
INSTALL a new camshaft position sensor. CLEAR DTC. TEST the system for normal operation.

M3: CHECK THE CAMSHAFT POSITION SENSOR SIGNAL GROUND CIRCUIT FOR OPEN
1. Measure the resistance between the camshaft position sensor electrical connector PI11 pin 2, (NY) and ground.

Is the resistance greater than 10,000 ohms?

Yes

REPAIR the circuit between the camshaft position sensor electrical connector PI11 pin 2, (NY) and the spliced joint PIS6. INSTALL the powertrain control module (PCM). CLEAR DTC. TEST the system for normal operation.

No
Go to M4

M4: CHECK THE CAMSHAFT POSITION SENSOR INPUT CIRCUIT FOR OPEN
1. Remove the powertrain control module (PCM).
2. Measure the resistance between the camshaft position sensor electrical connector PI11 pin 1, (WB) and the powertrain control module electrical connector PI1 pin 53, (WB).

Is the resistance greater than 10,000 ohms?

Yes

REPAIR the circuit between the camshaft position sensor electrical connector PI11 pin 1, (WB) and the powertrain control module electrical connector PI1 pin 53, (WB). INSTALL the powertrain control module (PCM). CLEAR DTC. TEST the system for normal operation.

No
Go to M5

M5: CHECK THE CAMSHAFT POSITION SENSOR INPUT CIRCUIT FOR SHORT TO GROUND
1. Measure the resistance between the camshaft position sensor electrical connector PI11 pin 1, (WB) and ground.

Is the resistance less than 10,000 ohms?

Yes

REPAIR the circuit between the camshaft position sensor electrical connector PI11 pin 1. (WB) and the powertrain control module electrical connector PI1 pin 53, (WB). INSTALL the powertrain control module (PCM). CLEAR DTC. TEST the system for normal operation.

No
Go to M6

M6: CHECK THE CAMSHAFT POSITION SENSOR SIGNAL GROUND CIRCUIT FOR SHORT TO GROUND
1. Raise and support the vehicle.
2. Disconnect the left-hand camshaft position sensor electrical connector PI10.
3. Disconnect both heated exhaust gas oxygen (HEGO) sensor electrical connectors PI6, PI7.
4. Disconnect the engine oil temperature sensor electrical connector PI12.
5. Disconnect the engine fuel temperature sensor electrical connector IL9.
6. Disconnect the cylinder head temperature sensor electrical connector PI13.
7. Disconnect the injection pressure sensor electrical connector IL2.
8. Disconnect the throttle position sensor electrical connector PI16.
9. Measure the resistance between the camshaft position sensor electrical connector PI11 pin 2, (NY) and ground.

Is the resistance less than 10,000 ohms?

Yes

REPAIR the circuit between the camshaft position sensor electrical connector PI11 pin 2, (NY) and the spliced joint P1S6. INSTALL the powertrain control module (PCM). CLEAR DTC. TEST the system for normal operation.

No
INSTALL a new powertrain control module (PCM). CLEAR DTC. TEST the system for normal operation.
