The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern
Vehicles with 2.8 LP1, 2.8 LAU, 3.0 LF1, 3.0 LFW, 3.6 LFX, 3.6 LLT, or 3.6 LY7 engines may exhibit two or more of
the following DTCs: P0016, P0017, P0018, P0019, P0008 or P0009.
Recommendation/Instructions
If the above concern is present, check for loose timing chains or tensioners.
If after following SI diagnostics the root cause is not found, the following may be helpful.
The reluctor for the crankshaft sensor pressed on the crankshaft may have moved.
Refer to attached photographs for exact location.
(It is possible on some applications to view this with a bore scope through the crank sensor hole without removing
the oil pan)
If the reluctor has moved then replace crankshaft.

Note: The distance can be offset either clockwise or counter clockwise. Both will result in these codes.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is
resolved without completing every step, the remaining steps do not need to be performed.
