Did some drifting in the snow tonight my 08 AT tls, I parked up with my friends and we chilled a bit and then I turned my engine off for about 15 min, after 15 min I started my engine and a check engine light came on?

Could it be because I switched to HFPC a few days ago and the O2 sensors are just tripping out?

Also I did put the tranny into 1st gear sportshift mode and did some donuts.

Before I go to my mechanic, what do you guys think it could be?

 

Don't mean to be rude, but WHY are you drifting in a FWD car in the first place?

There really is no point, unless you want to pretend like you're in Tokyo Drift and use the e-brake.

 

If it was the HFPC I would think it would've came on a few days ago when you first had it installed.

Who knows what the issue could be, but if the light came on because of your antics, you deserve it.

 

A check engine light can go on for over 2000 known reasons, none of us here, even I who is a certified technician for over 10 years can tell you why that light is on. You need to get it scanned. If you're worried about cost, take it to autozone they can scan it for you.

For the future, keep in mind that doing drifts in a FWD is a no. Get yourself a vehicle that can do so.

These transmissions are like glass, doing this in 1st gear and I'm sure you were bouncing off the rev limiter is a huge NO.

You also had VSA off. Lucky enough you didn't trip any VSA codes.

 

the price you pay when you're out there hooning.

 

This thread has 5 star potential.

 

This. Parts Source and maybe Canadian Tire can check/clear codes for you.

 

If the car is still driving normally, keep driving it for a few days and see if it goes away. Usually after about 4-5 engine starts and an unknown number of miles, any engine code that has cleared itself will turn off the CEL light. Even before it clears, it doesn't hurt to take it to AutoZone or Jiffy Lube (or any Canadian equivalent) and have them scan the code for you.

Also, you have a Type-S, which means you have nav, so if it's a new code that your car has never experienced, the nav system should have told you what the code is right away, along with what the code means. If it didn't, that means that the code has been triggered before, so you'll have to go into the menu, find the diagnostic messages, and you'll see the code in there. If there's more than one, you won't really be able to know which one came up, so you'll still have to get it scanned.

 

You said you have an 08 TLS which means you have nav, which means the car tells you what the code is. Why not look for yourself?
You can do some cool things in the diagnostic menu in the 07/08's. You can even erase the codes as well.
Woops, Bla8291 beat me to it^^^

 

For a second I thought I was just reading my comment over again haha.

 

Drift............uh you mean power sliding in the snow

Go get it scan from Autozone like others stated.

 

Why bother? The nav tells you the code.

 

GUYS my nav doesn't tell me any codes... I pressed all 3 buttons and got into diagnosis screen and it's simply does not show a "XM module" like everyone claim to have? Why doesn't my nav shows it?

 

Because you don't have an XM module, being in Canada.

 

How else can I see the codes in the navi?

 

I don't know, I don't have a Navi, and I use an OBDII device to read codes.

 

go to the same drifting spot and do it counter-clockwise. check engine light should go off after 15mins.

 

my side hurt

 

Lol you guys are funny -_- i went to canadiantire and bought an OBDII tool and scanned the code and i got P0174 which apparently well I THINK at least i got from mixing 2 types of fuel...

What i mean is i spent $10 in petro canada and bought 91 fuel, then a day later i went to esso and bought $20 worth of 93 fuel... and my OBDII scanner said "fuel is too lean" it was really confusing but i guess lesson learned... don't mix 2 diff fuel type from 2 diff gas stations ..

 

Not sure you'd be getting a P0174 out of mixing 2 types of fuel, though...

But you know, you could have told us you mixed two types of fuel to start with. It's hard to diagnose problems without knowing everything involved.




drift drift drift.... TOKYOOOOO

 

fuel is too lean because o2 sensors are failing.

not because of the mixed gas sources


actually, it IS BECAUSE OF YOUR HFPC's.
the o2 sensors are reading a lean condition.

mess with the o2 sensors, by unplugging them, plugging them. unscrewing them, screwing them in.

 

Why would they start failing out of no where? And I can't really just mess with the O2 sensors they really aren't that easy to reach... well at least the rear one isn't

 

He has XM. XM was introduced to Canadian models in 2007.
That's why they have XM roof antennas but 04-06 canadian TLs don't.

 

Because they're electrical components that just fail sometime. They're hard but check it out and see whats going on soon.

 

Do you have an idea where is the (bank 2) O2 sensor at? That's the one getting the error

 

this is the price we pay when we modify or deviate away from stock.
the car becomes "less reliable" per se.


the 02 sensor might not even be bad.
it's reading the correct levels of the car, ya know, because you do have High flowing cats....


I have pre-cat deletes.
once the car realizes that it's not reading the correct air fuel ratios; it'll throw the check engine light.
so, sometimes, I can trick the inspection and registration of the vehicle by resetting the check engine light.
it wont come on until after I pass emissions.

however; one day i took out the PCD's and re-installed them.
I must have positioned the 02 sensors differently or more tightly....
check engine light doesnt come on any more!!!!!

 

So how does everybody else on this forums with HFPC deal with this problems lmao

 

you definitely need to check out whats going on with the 02 sensors by visually inspecting it, then physically checking it, making sure its in there tightly.


if after physically checking it, and its still throwing the code, I would buy a new one.

 

bank 1 is near the firewall
bank 2 is near the radiator.

there's 4 02 sensors in total.
you'll need to know which sensor #1 or #2

It's not uncommon for an o2 sensor to fail. It may or may not be related to you HFPCs, but either way, if you replace the sensors you should be fine from then on.

 

Also, have you checked to see if your Noz button is stuck? I'd be weary because it may throw a "danger to manifold" code on your navi screen. Worst case scenario, your passenger side floor pan drops and your engine smokes like crazy once you come to a stop.

 

What justn said. Goodluck!

 

Thank you! When my mechanic was reconnecting my o2 sensors he gave me an advice and told me to wrap the wires with heat resisting tape? Because since I removed the heat shields it might fry my wires?

If i change my o2 sensors just as a precaution should I change all 4 of them just to be safe? And how much is an OEM one for our cars?

 

^nope, no reason to fix what's not broken.

after visual and physical inspection; I would only buy the one that is throwing the code.

Do you remember which sensor it was?
Bank 2 sensor __ ?

#9 #10 #11 #13 are the sensors.

 

No clue :/ my OBDII never said which one it just gave a generic code

 

Wouldn't high-flow/cat deletes cause O2 sensors to read rich? Not lean? And that's why O2 spacers are common with cat deletes?

 

I have had HFPC for over 3 years with no issues. I doubt its your cats so get the 02 sensors check like justn said. inspect them all; its only 4 sensors.

 

here in california, autozone will not read any codes for you, it has to do with some kind of law
