Headers = hot. Sensitive electromechanical sensors don't appreciate hot. So not the same failure mode as barfing oil, but premature failure nevertheless.

 

A not properly tightened filter sure as heck can, also you'd be surprised where compressor oil can end up. Mine was spitting oil everywhere and it ended up on the TCT. All over the wires for the VTEC solenoid.

 

Seriously doubting any of this. The torque sensor isn't that close to the header at all, it's about the same temperature over there as on the left side of the car.
And if you were having a leaking oil filter you will be in a whole lot more trouble than just a failing torque sensor. It's also something that definitely doesn't happen often but still torque sensor problems appear.

Oh well. In the end this useless speculation of blaming random things doesn't matter anyways. The torque sensor just goes out over time and it sucks.

 

It's not like the AC compressor clutch is close to the torque sensor or anything right?

there's no way oil from the compressor can wind up on the sensor. No way, ignore physical evidence, trust your gut.

 

lol. I didn't say anything about AC compressors on lhd cars... Just header and oil filter you guys were blaming for torque sensor issues on rhd cars...

 

Lot of issues can affect the torque sensor. Again it is the metal torsion bar etching a groove in the plastic slip ring because the grease dries out. Lubing the slip ring only helps if there hasn't been a groove worn in by the pins..

On the RHD cars there's different circumstances that affect the torque sensor. I don't have an RHD car, so I can't speculate what factors contribute, but for LHD cars the AC compressor is right next to the torque sensor.

That and driving through deep puddles and standing water are likely the main causes..

I know RHD cars tend to be UK cars which see plenty of rain.
