Fix thread plus intro: P032D solved

Hey all,
I've been lurking on the forum since June when I unexpectedly bought a tundra from my FIL. I wasn't shopping for a truck, and I honestly thought owning a truck would be a poor fit for my lifestyle, but its grown on me and I've bonded with with

This forum has been a huge help and great inspiration, so I joined today to say thanks and to do a write-up on a recent diagnostic and repair that hopefully will help someone in the future.

The Issue: Truck would infrequently go into limp mode and throw a code, P032D. I would clear the code and it would drive normally for 1-3 weeks before repeating the process.

All the research I did pointed to damage to the knock sensor wiring harness from rodent damage. I didn't find anyone reporting failed knock sensors... Anyways, order a harness, take down the intake manifold and find NO damage to the harness. I replace the harness anyways and codes returned.

Next up, I ordered a knock sensor (aftermarket) put it in and the code was permenantly resolved.

So, if you have a code for a signal condition on a knock sensor, this can be the sensor itself failing, duh.. What's weird is that almost all the reports you see on these codes are due to harness damage and not the sensor. In my case, it was the sensor.

cheers,

 

Welcome! Glad you fixed the issue.
