You are watching: 2005 nissan altima check engine light flashing
There space 2 possibilities. 1) Someone has been dickin roughly with the ECU setting selector and also left the in check mode. If this is the situation reset it back to typical mode.2) If nobody has messed v the ECU then you have actually a first trip DTC which means ya acquired a significant problem. In this case get the codes. If ya cant traction the codes it way your ECU is fried.
Flashing CEL is 9 times out of 10 a misfire in one or multiple cylinders. May be a bad plug, bad wire, bad injector, bad cap and also rotor, poor distributor. Most most likely not a poor ECU!
of food it"s not a bad ECU. As soon as your check engine light is blinking it method that the engine error is catalyst damaging. If friend still have your cats in then you need to drive the car as tiny as possible. And have the fixed ideal away.

Damn dude for your an initial post you provided a good response. And also since only a an extensive rich problem would quickly start to damages a catalytic converter, then he should follow up by analysis the spark plugs because that a rich problem as well, to check the suspicion.But if the messed with the ECU setting then it was to run in oxygen sensor test setting where the flicker correspond come lean and rich condition which the sensor is reading.

Coinicidentally, I had actually my ECU flash while driving because that the very first time yesterday as the auto was missing.Pulled over and read the codes- Cylinder 4 misfire.Plug looked okay so I changed the plug wire and also reset the ECU.No issues since but I"m wary.

Agreed! as soon as the car misfires, the piston is pushing the raw fuel the did no burn the end the exhaust and also this will kick your O2S"s and cats ass. So the CEL flashes to permit you know that the problem is serious.

well before it happened, I had intermittent rough idling as soon as i avoid abruptly or as soon as my a/c cuts off. It"s still contempt bouncy though but seems a little firmer. Ns still suspect an intake leak despite and currently have a FELPRO gasket yet am not willing to have it readjusted yet till it becomes terribly obvious. My mileage is quiet pretty shitty though, 215 miles to a tank(sigh).Will also test the No 4 injector.What carry out you think?
Thanks because that your help guys, however I still have no Idea what that is, i tried scanning the ECU, no power to it? idk... My cylinders are fina I checked the plugs, changed the O2 and also I replaced my cat... It"s tho blinking and The idle is getting worse. It putts indigenous 500 to 1500 rpm and then whatever is fine... Ns "m simply waiting to drop my new motor in

Well because that the third time.... You fried your ECU. It"s kaput, shorted out, dead. I don"t know how much fingerprint I deserve to be.

Considering girlfriend dont have a lift and I"m picturing this point falling on your face, you may want to plainly understand what is involved here.
I desire to clarification something. Once the CEL stayes on constantly the computer system is informing you the there is a trouble in one of the car sensors. The automobile however is still for sure to drive, however it will most likely remain in open loop, maybe sluggish, and also you will certainly get negative gas mileage. Once the light BLINKS favor it walk in your case, and also mine a little while back, it way that the ECU has detected a serious difficulty with the motor, and also the vehicle should not be driven. A missfire would pilgrimage the CEL, but wouldnt cause it to blind, if the missfire bring about damaged internals then her light will flash. DONT drive THE car until you sort things out.
Wrong. In this instance the ECU is fried since he can"t also pull the codes. The irradiate is blinking due to the fact that the vehicle is in fail-safe mode.
Hey Gfriedman, does it suggest to something in specific if i gain the shaky idle only once the automobile has been thrust for a while?
