Engine warning light after overrevved
 
Hi, is that normal that the engine warning light should come on after i over revved today? 2nd gear. All up to temperature.

Is it likely to go off after a few engine restarts?

Thanks

I'd get that read, a check engine light.. well.. usually means.. check your engine.

cubbs 09 June 2013 11:13 PM

True but really after someone with similar experience.

cubbs 10 June 2013 07:37 AM

Haha why? Bugeyes got problems?

Fudgey 10 June 2013 08:26 AM

Very common mate, shat myself the first time i done it mine.

will go after about 4 restarts. its for cam position sensor. when i get round to it ill take mine out and clean it, also add some more engine earths.

i have not even hit the rev limiter in mine and it does it, infact i dont even think ive taken it into the redline

dan-lincs 10 June 2013 10:01 AM

How far did you overrev it?

The Pink Ninja 10 June 2013 10:53 AM

They don't have I be over revved to come on, The bug seems to do it anywhere from 6k upwards.

dan-lincs 10 June 2013 11:17 AM

he said in his first post he did over rev it....

Is that the sensor in exhaust headers/ uppipe? My sensor was new in December with minimal miles since.

Thanks. Has anyone cleaned this before? BIg job? Will it be a fairly longterm fix?

Thanks

My camshaft position sensor error lights up on my bug anything over 6k........known Bug error and messing with the sensor doesn't always work.

Difficult to overrev the WRX out of the box as the rev limiter is set quite low. no point in thrashing the TD04.

Bob Rawle raised my rev limit :)

Sometimes cleaning works, sometimes a replacement works and sometimes a grounding kits works. Easy-ish job to do, especially if the aircon has gone:norty:

I get this and TGV Cylinder 2 volts low, both in the same area next to a big earthing point.

I've found the bugeye ECU to be a bit of a random fault code generator - it's a shame they don't have codes nuumbered 1-49 because I's use it to pick my numbers in a Saturday:D

Fudgey 10 June 2013 09:23 PM

not had a go at cleaning mine yet, but it (i think) is on the right hand side just by the cam cover. i cant see it being any other sensor that the CPS so ill give it a go. looks easy enough to get to.

JonMc 10 June 2013 09:25 PM

That's the one:thumb:

Fudgey 10 June 2013 10:00 PM

also, i can make earth cables etc up so is there any specific good places to put some?

or just an extra block to chassis type affair?

cheers :D

I can confirm spending £120 on a new sensor from Subaru doesn't work...

I can confirm it makes your wife wonder about your sanity though.

She clearly knows you can get genuine ones from Import Car Parts for about half that price :eek:

cubbs 10 June 2013 10:25 PM

Sounds like easiest option is not rev too high. I was chasing a bike over the mountain here on Isle of Man and was watching what he was doing more than what the revs were doing.

The light on the dash went out when the wife took it to work today. Ill get it plugged in to check code anyway.

Thanks.

Fudgey 10 June 2013 10:45 PM

p430 iirc?

it does make your arse cheeks clench any time a light comes on tho lol :cry:

Midlife...... 10 June 2013 11:01 PM

Post number 16 sort of sums up what the DENSO ECU does :)

Fudgey 10 June 2013 11:08 PM

Not sure, but on the TD04 I find it starting to run out of breath around 4.5 - 5k so ready for an upshift, unless of course you find you've run out of gears:eek:

Fudgey 11 June 2013 10:45 AM

Well i had a go this morning, didnt hit the soft limit, nor the hard but go it slightly into the red in 2nd... CEL on again now lol :cry:

if i get time at lunch ill whip the CPS out and give it a clean

Fudgey 11 June 2013 02:50 PM

ok, i popped it out at lunchtime (the CPS that is!)

10mm ring spanner with a bent end on it was needed. prise the cable clip off the oil filler neck to get access and unplug it, once the screw is cracked it came out with fingers.

the CPS itself was not really dirty, but i gave it a wipe over anyway but i did notice one side of it was a bit rusty/tarnished if that has anything to do with it?

also, there was some oil residue in the plug, so i sprayed some degreaser in there and onto the contacts of the CPS

i dont hold out much hope that its done anything really, so next step is to slap on additional earths.
