Great video. So many sensors on these TBI engines. My 89 Firebird has 3, one to gauge, one to fans, one to ecm.

They do have a lot of sensors. But they are pretty reliable for what they are.

Compared to modern cars, it's pretty minimal. A 2001 Mercedes S class has 60 computers on board. Imagine how many sensors come with that.

been having trouble getting my 95 vortec tbi to start when its hot and someone said it might be this sensor but I had no clue where it was or how to do it, so thanks for the info.

Even after replacing my CTS it wasnt working right and the ECM was reading high temps making it go into limp mode when warm. Zero power and timing really low. Unplugged my CTS.. plugged a paperclip into the pigtail connctor and no more issues. Will be finding the right resistor value to trick it into thinking its running at a warmer temp but not too warm. I have chased this issue 1 whole year. Stupid wiring short or something somewhere I suppose.

They can be a pain to trouble shoot sometimes.

So glad you commented this. Mine is actually doing this. I did end of replacing the sensor but I'm wondering if I screwed it in far enough but that limp mode is definitely how mine is reacting. It's being held back

It could be faulty wiring like I suspect on mine. For a check.. A paperclip works. I'm running A paperclip

Check your plug connection/terminals might not be contacting sensor. Replace pigtail and verify sensor is correct.

I found mine wrapped in tape while an aftermarket sensor was plugged in. Why would they wrap the original in tape and set it off to the side?

No idea why they would have it wrapped in tape and set to the side.

I have a problem with the car, when the temperature becomes moderate, then you step on the fuel, it cuts off and turns off, and if you turn it off and then turn it on, it returns to normal until you press half of the pedal, if you step on the entire pedal while it has not heated up, it responds well (tbi 350)89 van gmc

Sounds like it’s running super rich if it’s shutting itself off

THis one in the intake goes to the ECM if i am correct? THanks for the video. I need to replace mine!

@3rdGenC10s 2 жыл бұрын

Intake sensor goes to ECM, sensor in driver side head goes to gauge in dash.

It was installed before I got the pickup. It looks like it was just screwed through the rear cab panel.

@3rdGenC10s 3 жыл бұрын

You may try and heat up the area around the sensor and the sensors itself with a heat gun or something similar. Hopefullly that will break up some of the corrosion on the threads and you’ll be able to get it out.

This is way late, but how'd you get rid of that tube that runs from the tbi ring to the driver side valve cover? Mine is cracked and taped up. Thanks

I also have a Squarebody 350 TBI..when its HOT out, it doesnt start, dont hear fuel pump kick on..could changing this help?

@3rdGenC10s 3 жыл бұрын

I wouldnt think the CTS would have any effect on weather or not the fuel pump would kick on. I did have a issue when I first replaced my passenger tank and pump where after about 20 minutes of driving on that tank when it was warm out it would kill the pump, I replaced the selector valve for dual tanks when it developed a leak and haven’t had the issue since. No sure it’s related but that’s what fixed my issue.

I have a 93 corvette it has a code for a coolant temp sensor and it runs rich when it gets hot blows black smoke and stalls and doesn’t run again for a few minutes but I don’t thing my gage is reading wrong you think that is most likely the issue even tho the gage doesn’t seem off

@3rdGenC10s 4 жыл бұрын

The gauge is on a separate sender, it should be on the driver side cylinder head. The CTS should be on top of the intake near the thermostat housing, it tells the engine how much fuel, replace CTS and disconnect negative side of battery for 30 seconds.
