GDS, 0335 crank position sensor fault..

Found the CKP to have chaffed through the sleeve and expose all 3 wire inside that they short out to ground (engine block)

Replaced timing belt, drive belts, balance belt, tensioner, crank position sensor and blade for sensor

They had all that work done for one sensor?! Jeez.

My 02 just threw the Check Engine light tonight. She runs just fine... I'm thinking that it could be the CKP. Where is the CKP on the 2.7L delta engine?

If you are paying mechanic to pull timing belt covers and crank pulley; not much point to cut any corners. The labor is way more than the parts on this kind of job.

Reinstalling used serpentine belts also questionable if showing wear.

Just above the starter. You need to pull codes and look for a p-0335 before replacing on a lark.

It was a bad O2 sensor (P0051-Bank 2 Sensor 1)

Considering how bad it was (see picture) I am considering swapping all of them out. The two downstream ones may not be as bad, but they are also the more expensive ones.

Guess the photos didn't upload... :/ Needless to say this bad boy was pink and almost melted. I have a feeling it is an original.

Going back to this thread.... Would you recommend replacing my CKP? I've got 103K and it's pushing 12 years old.

2.7L will crack the outer tube and flake off, exposing the 3 tiny wire inside with each wire respective insulation falling off, now we have a 12V positive, 12V negative, and 5V feedback wires exposed and free to short to each other..

Simple inspect is to reach up in behind starter and feel the pigtail right tat the sensor body with pointy finger and thumb for cracking/brittle, falling off plastic outer layer.

Mine starting going bad at 5 year of age(03). Progressively got worse over the next three years till I read a post on here that was a duplicate of mine(jerks at highway speeds and stalls at stopsigns). Some have had total failure and had to have tows, so yes, I would change mine out a that mileage just for safety sake. Not that expensive and it's a DIYer.
