CEL

[twinturboboy]

I started heading home today from work and the CEL came up so I switched the car off then on and it was gone once I got home I connected the plugs and It came up with nothing - (the CEL flashed continuously)

any ideas - 2001 GTB E-tune BH

detected knock ?

i believe some cars do that . and it wont store it coz its not a fault

[twinturboboy]

well my car has had a history with knocking but it never used to show a cel? - when I first bought it it knocked real bad but after doing plugs and AFM it was better and I also did a tank with Octane booster and it seems to have cured the knocking pretty much

[Joker]

yea I\'m with that guy, not too much to worry about BUT keep eye on it/when it happens etc

[twinturboboy]

OK thanks guys

hm, i have the same problem and exact same car...

i purchased it couple of months ago and just recently the CEL came on but for me it seems to only be when it rains or after i exit motorway?

It only lasts for like 10-15 secs then goes off, but this repeats often..

any ideas? i have been filling with 98 only and i don\'t think its knocking, plus i havnt really noticed anything different in the way it drives.

I think it might be the electronic sensors, soon going to be faulty. I\'ve had that in my old Legacy. After awhile I went to a genuine Subaru workshop, they scanned the CEL and it came up O2 sensors and Air Flow Sensor, got both replaced on the same day. Runs mint after that, even gain extra power.

Just take it to winger, they hooked up there computer and told me what it was free of charge, turns out it was the o2 sensor on mine, however dont buy it from winger though $670 where as from strong for subaru was $250 for genuine parts.

well going back to this, every time now I start the car up the CEL comes on - but only when its cold and when you switch the car on and off it goes away - and its not coming up with any codes??

So I have booked it in to Nelson Subaru to get them to do a diagnostics check on Monday - will report back if you want me to

Yeah i was thinking something along those lines as well...

do you think it would be okay to just continue driving with a faulty sensor? or is it one of those things you have to fix asap.

appreciate the feedback

updates?

Don\'t trust the winger boys. What I meant is that, it\'s good to take your car down to Winger Subaru as they supply genuine parts etc but don\'t tend to leave your car at their workshop, their young staff/mechanic tend to take cars down for a boost. Even to get lunch etc. I\'ve always booked in early in the morning for check ups etc.

Thats a pretty big generalisation. Theres no Wingers in Nelson anyway.... Never really been a fan of Nelson Bays Subaru though, never really interested in helping out on small things. Nathan (I think?) is pretty helpful though and is pretty clued up when it comes to Subarus.

Hardly think so.... anyone doing that sort of thing soon gets fired INSTANTY

and whats the difference of them road testing ya car and "boosting it" as you say, and you "boosting it"

Yep Nathan is the best guy there - I do know what you mean all they really care about is getting $$$

Thats the reason why l won\'t go back to dealerships and especially large workshops, from previous experience, my mechanic is a small owner/operated workshop with an appreciation for subarus and you know whos going to be working on your car

[twinturboboy]

Well i got the Legacy back today from Nelson Bays Motor Group and they came up with the following:

Fault: Engine check light on

Carry out Diagnostic checks for fault,

Code P1130 present

Sensor 1 Bank 1 Sensor 1

A/F Ratio Sensor failure - req replacement

Total cost to get this done was $97.70

so I asked them the cost do change this sensor and they said 660 inc GST plus 1 hr labour, I rung up Armstrong Subaru in CHCH and got the sensor for 460 and have decided to replace it myself

what do people make of the code they came up with - no wonder I couldnt diagnose it myself the standard way

also where abouts is the A/F Ratio sensor located? and will I need to get them to reset the ECU properly with their computer after the new sensor is fitted?

Cheers

[duddley]

They are the ones up the front I think and when the mechanic did mine he just started the car and the light went out.

[Pappu1]

Yours is a rev d perhaps hence that code

Anyway the AFR sensor is in the extractor system before the turbo

Not too hard to change tho

[twinturboboy]

two more Qs

-will I need Nelson subaru to reset the ECU with their computer after fitting it?

- I already fixed the fuel leak it had (the hoses under the manifold) and since the fuel ratio sensor failed the smell of fuel came back a little bit through the air con - so will the new sensor fix this issue? - (the guys at Subaru thought it would)

[Marky]

A) probably not you can DIY that

B) if the sensor was stuffed it would have always stuck to a richer state of tune - even at idle - so yes that would possibly explain a petroley smell

[twinturboboy]

would I reset the ECU via the two plugs? - Iv done this before but Nelson Subaru says It wont clear the codes properly and it would need to be done with a computer?

[Kiwi_Fozze]

On revision d legacies (2001 ish) and newer they have to be cleared via computer...

Same with the v7 imprezas and facelifted foresters

[twinturboboy]

Yeah ok maybe I will get it done with them then - mine is 2001 E-tune Rev-D

Incorrect - they can be clear via check mode plugs
