My 2001 Nissan frontier wont shift out of second gear the od light keeps coming

Here’s my thought: go back to your technician and have him run the wire pair for the throttle positioning sensor (TPS). It may take some time as the tech will have to go to the TPS connector base and run each section of the circuit to find where the ground is occurring.

No, there’s no easy fix for this. It just takes scut work and time. However, if you want your transmission functioning normally again, the only way to do this fix correctly is patiently and step by step. It may also be costly because it could take the tech several hours to do this work. I can’t begin to estimate the number of hours needed because I don’t know where the break and ground might be.

You might get lucky and the break could be right at the terminal points for the TPS. If that’s the case, the tech may be able to cut out and replace only one section of wire, though, knowing what I know of electronics, the best bet is replacing the wire end-to-end, just to be on the safe side. If your tech is good, though, and he recommends only replacing a piece of the wire, then I would go ahead with confidence.

Getting back to costs for a minute, by the way, I use a base figure of $150 per hour time (it’s an average of hourly rates at shops across the country). If the fix were to take four hours, it will cost you about $600; 12 hours will cost about $1,800, more or less. I am listing the figures here to let you know what you stand to spend, if your tech can give you an estimate of time.

Let me know what the results are, I am interested.
