I have a 92 civic DX, 90k miles. I would say once every 2 months the CEL light comes on...I immediately turn the car off and turn it back on and it doesnt come on for like another 2 months.(and I drive it a good amount)

WHat would happen if I tried to check the code with the 2 pin connector tutorial? I guess what im trying to say is what happens if your car is not throwing a code, but you check for one? WIll the CEL still flash, or just do nothing?

 

The code would still be stored in the computer.

 

I check OBDII cars often and I've scanned cars that were supposed to have recently had check engine lights on, but it's now off. Sometimes something shows but it usually doesn't. I believe the CEL still usually lights if you have a stored code.

This could be different for OBDI cars though.

When connector is jumped:
No Codes Present/Stored = Solid CEL
Code(s) Present/Stored = Flashing Pattern

Next time the CEL pops up while driving, don't turn the car off. Just pull over and jumper the connector to read the code.

 

not tryin to thread jack, but is it bad to leave it jumped?

I would imagine it's not best to do so. The jumper is also intended to prevent the ECU from changing timing while you adjust it manually via the distributor's rotation. What I do is install a switch (glovebox or elsewhere) to flip as needed to check codes or adjust timing.

thanks, im just waiting to get a new ECU to clear my codes, and ill remove it, but I don't mess with timing... for now... Once again, thanks and sorry for jacking.

 

thanks guys.

 

yea mine comes on every once and while also and turn it off then back on with no cel. I still check it and it steady comes back 1 and 43 so i figure 43 is making 1 come on in my obd1

 

still very cool that even with old cars you can check the codes with a paperclip...haha
