Bitten by the P2135 snake. UPDATE

[94Eddie]

A couple of days ago I saw the dreaded wrench light come on in the Mountaineer. Then the computer reduced power to the point I could walk faster than it would drive. Luckily this happened pulling out of the driveway so I thanked the car gods for their impeccable timing to my benefit. Pulled some codes and P2135 was showing up in a couple of places along with a torque miscalculation error (P061B). Looked into this a little and decided that the ammo to use in the parts cannon would be a latest and greatest throttle position sensor (TPS). It could have been the pedal position sensor but these don't go bad all that often. Mind you there are three versions of the TPS to choose from. The one to use is the latest which is Motorcraft part #DY1164. This is what I heard from my repair guru FordTechMakuloco. The faulty one was the original TPS as the bolts had the paint marks on them to show they were torqued to spec. I believe it was the second iteration of the three. I fired the parts cannon this afternoon and, after a thirty minute test drive going well, I think I hit the target. Between buying the part ($78.60) and paying for the gas to do the test drive I probably spent $500 for the repair in total.

Also, with all the talk lately about deteriorating wire insulation on 4th gens, I had a chance to check the status of mine at a few connections near the throttle body. Luckily everything seems to be in good condition. Although the electrical tape Ford used to wrap the wires just outside the looms is not the best and is somewhat brittle. I'll update this post if swapping the TPS doesn't fix the issue long term. I just wanted to document the problem along with the fix for future reference by others.

You know - the 2010 doesn't require premium - you could have been in it for only $475 or so......

Shouldn't be here except for a vehicle now and then.

In my area it was unseasonably cool and balmy today.

I am circling back to this thread to give an update. As I stated, I replaced the TPS sensor and all seemed good for about 2-3 months. Then I started getting the P2135 code again intermittently and then more frequently. I checked the wiring again and found no issue and I started thinking that it might be the throttle body plate was lose and maybe was preventing the intake air from being metered accurately. I took it off and messed with the throttle blade and there just seemed to be a little too much play in how it was moving. I decided to get a new Motorcraft TB. Once I compared the new one to the old one it became apparent that the new one had a noticeably tighter tolerance with the throttle blade. It was less Lucy goosey. I installed it in late October and decided to put some miles on before posting the results. Since the new TB was installed I haven't had a single issue with any TPS, TB or accelerator sensor codes. Now that I have said this it could jinx me and the codes will come back tomorrow. For now I am going to say the TB solved my issue. I wish I would have put the $83 paid for the TPS toward the $180 TB but hind sight is 20/20. I should add that it is possible I got a bad TPS but I think the odds of this are small.
