EGR delete and check engine light hack

[@321CatboxWA]

For a stubborn check light , locate the lamps positive wire lead and sever it before the cluster gang connector . Next locate the Alt./ Gen./ battery lamp positive lead and tag the positive wire from the check lamp to it in parallel . Now the check engine lamp will operate like it should when no codes are present ( on with ignition ,off when running ) .

Won't this just turn off the annoying check engine light, but not help you pass an inspection?

I always thought about trying to reroute my EGR tube to the exhaust before the O2 sensors in a low pressure area, seeing if that would work.

Could have put a resistor in the circuit at the PCM

[@JCnordic2983]

So why not connect a small light in the enginebay where the solenoid wires ?

Give him a medal.

[@forgottenknowledge8917]

So the test light acts as a resistor. Nice. You can also do this on pesky oil level sensors that nobody needs.

That beast is still moving? You’re a mechanical genius brother

[@randy1ization]

doesnt the computer look for a difference in egr gas at the 02 sensor when it runs its periodic tests?

[@871jamie]

1993 was still OBD1 so no. That started with OBD2.

[@phoqueewe7230]

What about pre-detonation and pinging from the delete without tuning it out?

[@Karlwallin]

a resister would work as well instead of the test light no?

[@user-qx1wl2um2k]

Is it possible to block off the egr port and leave the electric plug connected to a good egr valve laying off to the side to fool the computer?

[@crazyDIYguy]

Somehow the ECU knows, on the newer vehicles anyway. You'd have to look up your specific manufacturer ecu strategy, personally I block mine off, and I delete the check engine with specific programming by reflashing the computer.

Awesome!!!

[@stephenhans189]

Does it come on at full throttle? Thanks

[@khills1181]

Why not just leave the egr valve plugged in and zip tie it to a bracket or something?

[@cuby_9467]

Do you think this is possible on obd 2 from 1996?

[@aliasjonespickleguy7017]

Didn't he steal the chipmunks?

[@Matthew-ib2kz]

Dudes engine is in his trans tunnel 😭😭

[@caduceus33]

It's in da dog house!

[@tyronebiggims1613]

Goofy.. un plug bulb in dash,,

[@phoqueewe7230]

Ah, so no check engine light for anything that may matter. Talk about Goooooofy!!!

[@Jbainbridge5]

Genius.

Thanks for the hack! This opens doors to so many possibilities now 🫠💯💯💯
