Help.. Check light, why?

wtf

 

Did you ever get this taken care of? I got a P0170 code the other day. Same deal w/me, no vacuum leaks, cleaned out MAF, BUT I ddin't look at the o2 sensors. Where are they located on the truck? What about the fuel filter? You know where that is? Thanks for your help!

 

That made me laugh!

 

any idea how to fix P2714??? My Ultragauge is reading that; took it to the toyota dealer and they said a new transmission may be needed...(i actually bought a warranty 'cuz I've never had good luck with the transmission)

 

I believe thee is a TSB on that code that says first step is to reflash the PCM. You will need to find a place that can do that for you obviously.

 

I just fixed my problem with the check engine light...Duh, Bad aftermarket gas cap!!!
Always check the easiest first. Hope this helps someone else.

 

About the CHECK ENGINE LIGHT : on my 2008 tacoma (45.000 miles), I had to replace twice the pump module fuel RSV (in the tank). I don't think it's normal. Did somebody meet this issue before ?? And would somebody have an idea about this problem ??
And, one month before the failure of the pump, this check light turn on.....
Thank for your suggestions or comment.

 

If you don't really care.. about it being on.... Just unplug the battery, and the light wont be on there! (wouldn't recommend it, you'll never know what was actually wrong with it..)

 

how to check air /fuel sensor heater circuit response(bank1 sensor1

 

Nice posts, won't be wasting any paper when I print that one. lol

 

NICE POST

 

Gents,

Think I have a similar but before I go replacing expensive parts I wanted your thoughts. Attached is a snapshot of my error codes

 

Well if you overfill your gas tank by clicking it multiple times to force more gas in you can mess up the carbon canister happen to me doing the frame replacement they tilted my truck to far with a full tank of gas and caused the same condition still fighting Toyota trying to get the to fix it. 500 dollar plus part.
This causes the engine light to come on after resets in the 300 plus mile range. Small emissions code.

Ghost Pirate Out

 

Can I play on this mummified thread?

It's never a good idea to try to round up when you're filing up the gas tank. It will eventually lead to premature evap canister failure. Once it stops, leave it be.

So, yeah.... any news on the fix OP?

 

Good God...I just liked a response on a post that's over 6 years old...who opened this casket?

 

Perfect.

 

I am getting a P0158 code as well! I just replaced both downstream o2 sensors, ignition coils, and spark plugs (used all denso oem parts). I checked the resistance across the o2 sensors and they read around 16 ohms at 90 degrees Fahrenheit(means they're good). I logged both downstream o2 sensors and found out that sensor corresponding to bank one would have a voltage that varies. o2 sensor correspding to bank 2 holds at a constant voltage (around .9 volts)I will post pictures to show this. Does anyone know where else I should go from here as far as diagnosing goes?
