Check Engine Light On

Hello

The check engine light came on and stayed on this morning on my '97 SW. The truck seems to run fine. Any thoughts on diagnostics/repairs I can do myself? I don't have an OBDII code reader.

Thanks! Dave

Checker / Kragen / Shuck will lend you a code reader for free (you may have to leave a deposit) and will tell you what to do to fix it. Who says nothing in life is free?

If she's still running fine, probably an 02 sensor.

Ron, Dave

Those are great suggestions. I suspect it's an O2 sensor too. I just had one replaced a couple of weeks ago. I'll try Kragen and maybe AutoZone to borrow their OBDII reader.

Thanks. Dave

Check the engine, I think thats what it means. On a similar note, if my wherlydo is affecting my whatcha and making it make glubba glubba sounds coming from the back of the thingy, what would you all recommend? If it helps, the truck has been driven before, both at night, and in the day.

Dave J. check the code and find out what it is, then reset the ECU and wait for it to happen again before replacing parts.

Dave since it is happening at both night and day I would say that 2 of your sparkplugs are missing and the coil on your TDI is bad. Try adding sparkplug gap filler to your ECU.

Thanks Mike,

I'll definitely try that.

I assume that Kragen etc. will be able to tell me what the codes mean????. Anyone know of where I can find a list of codes and their meaning for my '97 D90?

Thanks as always! Dave.

Jeez! Ever hear of searching before asking?

I have often used ACME Premium Spark Plug Gap Filler with excellent results! In fact, I have overgapped ALL my spark plugs from the Corolla to the TR6 by about 1/4-inch and then filled in with ACME to the precise gap called for.

Be sure to get their Premium Jig. Makes a damn easy job of applying the filler. Fully digital controls - just enter the desired gap and you're there in no time! Of course, you can do it manually but it's a bit of work.

I picked up an OBII reader for about $100, so I can check and clear them anytime. 'seems like a good investment, since it can be used with any car from '96-on.

It could be lots of things. Mine has been throwing a bad speed sensor code every once in a while, that I haven't gotten around to fixing.

Thanks everyone for the help.

Borrowed the OBDII reader from AutoZone and read code P1193 - O2 sensor heater circuit open downstream. My shop replaced an O2 sensor a few weeks ago after reading this same code. I cleared the code, and I'll wait to see if the check engine light comes on again. Will also call the shop.

Thanks again. Dave.

You have 4 O2 sensors in a '97. 1 ahead of, and 1 behind, each cat converter. That's a code for one of the "downstream" (after the Cat) sensors. Maybe the dealer replaced another one; are you usre it's the same code?

Hello,

Definitely the same code as before; it's written on the repair records. It's also easy to see which of the two sensors (behind the cats) was replaced. So, I'll wait 'till the check engine light comes on again and take it back to the shop. Payed about $240 (ouch!) for the sensor last time.

Thanks. Dave.

Good suggestion. I bought a couple of O2 sensors from these guys on Friday. Good to have spares. Dave.
