Try reseting the ecu

Be Warned! that you'll have to do a window reset.

Gotcha, how do i do that? disconnect the battery?

homeryansta · 03-24-2012, 01:14 AM

My sentra does that everytime I drive it through the carwash. Limp mode....

Yes, Disconnect the negative cable on the battery

For the Window reset?

Hold window button down for 10 seconds then up for 10 seconds. Repeat for other window, that should reset the auto up/down feature.

Disconnecting the Battery to reset the ECU only worked temporarily and then the "Service Engine Soon" check light went back on again. I'm going to try disconnecting the battery for longer to see if it works tomorrow.

I did notice although the engine runs relatively smooth, there was an instant where I heard a sputter and that was probably when the "Service Engine Soon" light came on again. hmm....

It does take a while for the ecu to adjust.

I would just drive it for awhile, and turn it on and off for a couple cycles to see if that clears it

thanks again. I'll try that again in a bit. But it sounds like all the electronics should be dry by now and don't need to be air-ed out anymore?

I was able to drive it smoothly at any RPM, the only problem I have is the Engine Service Soon light on - which hopefully it's something the ECU can reset.

Like I said it may just take some time of driving and engine on and off cyles to go away.

If after 3 days of driving it it doesn't go away? You may have to have the dealer check and clear it

MaDMaXX · 03-24-2012, 02:08 AM

Um, yeah, i'd go get that code pulled to see what it thinks is wrong.

scruffydog · 03-24-2012, 02:30 AM

I just plugged the battery back in and I was able to clear all indicators as if it's fine, but I got Limp mode at 3000 RPM...hmm any idea what's wrong with it? I unplugged the battery again, hopefully the Limp Mode gets removed like earlier when the Traction Control & VDC indicator cleared. I was able to drive the car fine earlier but the only problem I had was the "Engine Service Soon" indicator stayed on. Now I was able to reset the ECU and clear all the indicator but for some reason the Limp Mode is still there. I tried turning off the car and back on several of times, still no different.

As for the code, since the "Engine Service Soon" light is off, there probably isn't any code to read anymore.

I once again took out the MAF sensors to dry out some more and also the Air Filter, but I'm pretty sure it's now dried rather it's an ECU related issue, something is not clearing.

zguynate · 03-24-2012, 09:49 AM

I would get the codes read and start there. Maybe a sensor is shorted out.

370ZilverZ · 03-24-2012, 09:58 AM

Use compressed air or a heat gun and blow out all the connectors. I had a shop install a sun strip on my windshield yesterday and my rearview mirror connector was full of water when they finished and it shorted out my back-up display and homelink. Fortunatly I was able to dry it out with a heat gun and it works properly again. Won't be using that shop again either. Water and electronics never play well together.

Take it to the Dealer and let them read the codes and determine the issue.

scruffydog · 03-24-2012, 01:31 PM

the dealer found the CAM or CAN Sensor (the service advisor just said something wasn't communicating properly, I think he meant the Camshaft sensor) to be at fault and is currently ordering one for me under warranty.

My car had a hard time starting up this morning, it would sputter for the first 15 minutes then it was at a limp mode, no check light.

Then i drove it for 30 mins and the car did not have the limp mode.

I then drove to dealership, stopped turned off the car, hard time starting, i told them i wanted checked out with a Diagnostic tool. He said something to do with a cam sensor needed replacement. Since they didn't have any in stock, i would have to go back for replacement when they have it.

The car didn't crank for minutes, then finally started up. VDC, Traction Control, & Service Engine Soon indicator came back on and Limp mode is on. I'm going back on monday to get my sensors replaced, but anybody have idea where this sensor is located? I would like to take it out and dry it so I can drive my car in the dealership when the new sensor arrives at my dealer. Cheers
