Fault Code

Possible cause

Action

P0068

Manifold absolute pressure sensor correlation error with throttle position sensor

Check for air leak at the throttle body/transition piece to cylinder head face.

Check for trapped, twisted and damaged MAP sensor hose(s).

Check for air leak at the MAP sensor hoses.

View and note 'freeze-frame' data if available.

View and note 'sensor' data.

Make sure sensor connector is secure.

Disconnect the engine ECM and proceed to pinpoint test 1:

Camshaft Timing Check/Adjust, as described in the service manual

P0069

Manifold absolute pressure sensor correlation error with ambient pressure sensor

View and note 'freeze-frame' data if available.

View and note 'sensor' data.

Make sure sensor connector is secure.

Disconnect the engine ECM and proceed to pinpoint test 1:

P0107

Manifold absolute pressure sensor 1 short circuit to ground

P0105

Manifold absolute pressure sensor 1 open circuit or short circuit to 5 Volt sensor supply

P1105

Manifold absolute pressure sensor 1 pipe malfunction

Check connection/condition of pipes from MAP sensors to throttle body.

Test

Result

Action

1

Check cable and terminal integrity:

- Engine ECM pin B23

- Engine ECM pin B18

- Engine ECM pin C29

- MAP sensor pin 1, 2, 3

OK

Disconnect MAP sensors and proceed to test 2

Faulty

Rectify fault, proceed to test 4

2

Check cable for short circuit:

- Engine ECM pin C29 to Engine ECM pin B23

- Engine ECM pin C29 to Engine ECM pin B18

- Engine ECM pin B18 to Engine ECM pin B23

- Engine ECM pin B18 to ground

- Engine ECM pin C29 to ground

OK

Proceed to test 3

Short circuit

Locate and rectify wiring fault, proceed to test 4

3

Check cable for continuity:

- Engine ECM pin B18 to MAP sensor pin 3

- Engine ECM pin B23 to MAP sensor pin 1

- Engine ECM pin C29 to MAP sensor pin 2

OK

Renew relevant MAP pressure sensor, proceed to test 4

Open circuit

Locate and rectify wiring fault, proceed to test 4

4

Reconnect harness, clear fault code and run engine.

OK

Action complete - quit test

Fault still present
