check engine light on
 

my check engine light is on. I did a cel check by jumping the diagnostic box.I am getting one long flash followed by 6 fast flashes. about three months ago I replaced the EGR valve and 02 sensor. I cleared the ECU but it comes back at start up. any suggestions
thanks
Jeff

1) troubleshoot the 16 code again. Especially try to find intermittent wiring problems.
2) swap ECUs to be sure it's not the ECU itself.

Hey Dave. Thanks for the reply. I reset the ECU and it drove fine until I got off the Freeway and stopped at a light. then the light turned on again. I am going back to the shop and have them look at it. I might have to do the EGR relay thing to cure the problem or change the ECU. I need to find a N3A4 ECU for an auto California car if anyone has one send me a PM.
Jeff

does you cel come on and stay on?
i was driving around and mine would come up randomly
it threw only the egr code at the time
but since the cel never stays on solid,ill leave it as is...doesnt bother me too much

Hey jic. when my cel comes on it stays on until I clear it. then it runs fine and comes on randomly. right now its off amd working fine. its driving me nuts!!
Jeff

yeah mine just stays on a few seconds and turns off...some advice i got..just clean the egr vavle and it should be just fine

I replaced the EGR and now the problem is back. the shop said its in the wiring harness and may need a relay installed to correct the problem.
Jeff

I'd just install a relay or find a non-Cali ECU that doesn't check the EGR valve. That whole checking system is so crappy anyhow, there's no good reason for it.

Dale

Probably a wiring problem. That's what happened to me.

yeah i think dales got the best solution
if you dont need it and its bothering you, get rid of it
im jsut too lazy to install a relay on mine and since mine doesnt stay on at all times

Hey thanks for the advice. anyone know where I can get a non-cali ECU for an auto trans car. my ECU is # N3A4... I think the non-cali ECU is # N3A2.
