no start,cps questions

El Supracabras · 06-14-2011, 06:51 PM

+1 about the wiring. It is the supra's weakness. If you didn't take out the CPS it is not likely it's alignment will be the problem.
If you need to drive it right away, just cut the connector off and use heat shrinking butt-connectors to connect the wires together until you can properly repair the connector. This is not the cleanest way to repair it, but it is very fast, cheap and effective. I have also successfully replaced this connector with Weatherpack (GM) 4 wire connectors from NAPA. It is a much better connector.
If you have the time to repair it cleanly, back probe the connector with a ohmmeter to find the bad connection and replace or repair the offending pins.

I really appreciate the info. I will be getting a weatherpack GM 4 wire connector this week and swap out the old one.

el supra. wanna touch more on the wiring of the cps. I wanna do that. same with my afm.

Not much to touch on as far as the wiring goes, it's only 4 wires. Just do them one at a time if you don't trust your memory or schematic deciphering skills. If you just want to change the cps connector I'm gonna do one this week, I will take some pics. It's very easy and I will be using the Weatherpack connector.

yea please, keep me posted. So what you just cut it from the connector and wired them in again one at a time.. I could do that. Was thinking about ordering the replacement from driftmotion.

The one on drift motion is only the sensor connector. It will look nice and original but wont help at all if the harness connector is damaged. Great price though, if they had both sides of the connector I'd order a bunch of them.

not to hijack this thread but..
I replaced my afm and that solved the problem of it running like crap, untill it's cold outside or cold start. So im leaning to the wire or the idle air control.
I have to search to see how to clean my idle air.
