Hello,

I have a 86 trans am with EGR Valve and a temperature sensor on the EGR Valve.

There are many EGR Valves, I don't which one is the good one with the place for the temperature sensor on it ?

DO you have a part number for the temperature, I found this but not sure :

And do you have a part number for the control valve ?

Thanks for your help

That is possibly your best chance at finding an EGR temperature sensor. The EGR Diagnostic Switch is a GM 14087416, AC/Delco 212-337, or Standard Motor Products ETS-2.

The EGR valve itself is a negative backpressure type, It is a Standard Motor Products EGV393, still available some places.

The EGR vacuum solenoid is GM 1997169 (Sorenson 7799607), and is still listed as available.

I used that exact style EGR temp sensor, all you need to do is cut the plug off the end and splice into the old wire and your all set. This is what finally cured my Code 32. You can save almost $20 if look on eBay or other Corvette places.

If you can’t find the EGR valve Vader mentioned I used AC Delco 214-5538 from Rockauto and had no issues. It has the temp sensor threaded bung and actually clears the plenum because it has the EGR port set up like OE unlike many aftermarket that have a plastic nipple on the top that can possibly interfere with plenum clearance. I didn’t like that it was made in China but it is what it is. Also my car is a 88’ L98.

The last year, I replaced EGR + Temp. sensor with:

EGR Valve Standard Motor Products EGV393 +

1986-89 Corvette New EGR Sensor Replacement Switch GM 14087415

This Corvette sensor has a shorter wire that original Trans Am sensor, but I ran the wire under fuel rail and connect it with the original connector with no issues.

It works for me, but today I've pending the legal smog test, but in the last test, the NOX was approved with the old EGR blocked by previous owner

You can use a later 90-92 egr and delete the malfunction code 32 as a option
