The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
A dealer may encounter a vehicle with a rough running engine, crank no start, or a DTC P0335.
The crank sensor connector may be loose, not plugged in completely, or the connector retaining tab may not be locked.
Recommendation/Instructions:
Complete the current SI diagnostics for any trouble codes or symptoms found. If a DTC P0335 is found with a stalling or no start condition, inspect the crank sensor for a loose connection. Also inspect the crank sensor wiring for short to ground, pinched wiring, or chafes.
If there is no damage to the crank sensor connector, terminals, or wiring, properly connect the crank sensor connector, and evaluate repairs.
If there are no wiring concerns found, and the crank sensor connector was properly installed, replace the crank sensor.
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.
