Title: TPS TEC
Post by: kjhansen on December 04 2021, 05:16:48 PM

Steve, in a previous message I said I had a TPS TEC (came on the car) and you said it's better to take it off.  I quote:

"take the tps.tec off.  It does nothing but it could screw up something.  As long as the tps is set between .36-.46, it should not affect the idle once the engine has been shut off and restarted.  Floating around while running will make it feel different, however.

The tps/tec was sold in a day before people understood how the ecm fuels the engine.  It was a totally meaningless product but people did not know that then."

I've been meaning to take it off but haven't yet.  It has wires running from the plug that goes into the TPS that are the same colors as the wires running INTO the TPS plug (see picture).  Do I just cut the wires that go to the TPC TEC or do I need to find a stock TPS plug as this one is obviously modified for the TPS TEC.

easiest is to just snip them off

Tried snipping the wires.  That took the TPS out of the computer loop.  Putting the TEC back in fixed the problem.  What did I do wrong?

Is the TPS TEC spliced into the harness or does it plug in line with the harness? I've seen them both ways.

Good question, Jeremy.

Originally, the user, unplugged the tps connector from the tps.  Then he plugged the tps tec into the tps and then reconnected the factory tps connector to the backside of the tps tec.  To remove it, it should be just be unplugged from the tps and the original plug reconnected as it came from the factory.

As he was asking, I figured he had been hard-wired and it may be, but either way, it needs to be removed and replaced like it came from the factory

It's hardwired into the TPS connector.

Steve and Jeremy. Can he not just solder the original wires back together?

Yes, that is the easiest way.  Just cut the three wires going to connector some way away from the connector, and cut the three wires from the original factory wiring harness.  Solder and heatshrink the connections and get on with the next problem :)

There always seems to be a next problem doesn't there?  In this case, I've stopped the oil leak from the passenger side valve cover gasket, but it's still leaking oil from somewhere else.  Look for a new thread!
