TPS reading eratic

sharper · Post by **sharper** » Sat Jan 12, 2008 4:09 pm

Noticed on a recent datalog that my tps reading is fluctuating, reading down to 87% at wot, in spikes all over the place. Had to recently replace with an omni-power unit. Any ideas

Is your TPS sensor making contact with anything, like the hood?

No its clear of everything. Datalogged a few runs today and on 4 out of 5 times the TPS only deviates 3-4%, and then on that 5th run it deviates to below 85%. Have attached a datalog to show.
Recently replaced with an Omni power uni?? Any way to check it.

It sounds like you have checked it and it had been damaged or is faulty. I would suggest contacting Omni Power. The only other posibility is that you have a wiring fault or a bad ground somewhere. Try the sensor in another vehicle.

New sensor is on its way, still under warranty, Kingmotorsports handled it no problem. Will update when new one is installed.
