Hi all,

Before I go down what seems like the obvious but wrong path.

Just got a new tips sensor board from 914rubber.com.

When installing, shouldn't remove the tps assembly from the engine or leave it in place.

I was thinking it may need to come off but don't know if that opens a can of works in terms of linkage,gaskets, etc.

Thanks,

Mike

Thanks. Changed it this evening, have not had a chance to test drive. Could definitely see the wear on the old one even with only 45k miles on the odometer.

One bit of oddness I experienced on my '74 2.0

I replaced the throttle position circuit board. Put the TB back on car, hooked up some jumpers and could not get a reading other than 1.

Figuring I might have the jumpers wrong I again removed the TB. Jumpers were correct and I was able to calibrate on the bench. Left the jumpers in place, put the TB back on car. Checked reading, still zero.

I now hook the linkage back up and notice the reading is back at 1. Loosen the screws, go to adjust and same as before, only shows 1 no matter how I turn the assembly.

Seems to be OK with bench calibration but not sure why I can't seem to calibrate on the car?
