Occasional engine light

[losh1971]

Little orange/yellow light that stays on before going off when you first start the car is coming on every now and then, while driving. Reckon I have seen it come on 6 - 8 times over the last 2-3 weeks. It goes away within a few seconds. Car still runs and doesn't miss a beat. Should I be concerned? Seems to occur around 2000 revs or lower. What causes it to come on, just failing sensors??

Cleaned out all the gunk in your throttle body and plenum lately?

Check for codes with a paper clip

Never cleaned the TB on the ute. What gaskets will I need? I asked Repco about getting the gaskets and he wanted to sell me a whole set, like 80 bucks worth as he didn't have a listing for just TB gaskets.

I will run another scan. Last time I run the scan nothing came up except security disabled. Yet my TPS was buggard, hence I don't have huge amount of faith in scans. But will try regardless.

Mate you will save yourself a ton of mulla by getting a diag cable and software (plus a laptop if you dont have one)
I got a netbook for $80 cable for 70$ and software well I spent 120$ as I tried a few different ones....
Anyway quite a few errors dont flag a fault till they fail or if they are not mission specific...random ones for me in the past was O2 sensor...temp sensor..trans slip..tps...

Yeah I have a cable in my watch list. Can i just plug it in to a regular laptop? What port does the cable go into on the laptop? I have had the trans checked out and its in good condition. Had new solenoids fitted last year when the tech serviced the trans. Pretty sure the temp sensor has a dodgy plug. Previous owner had put blue RTV on it but I've never checked it out. Is the plug replaceable on the temp sensor? Could I chop the plug of a wreck and replace mine? Or would it be a matter of splicing in the wires? I replaced the cat back would that have any affect on the 02 sensor?

 

[losh1971]

02 sensor is on the cards as i dare say im on the original one still. But i may wait until i fit headers as i don't think it will cause the ute to break down.

yeah it just plugs into a usb port..best bang for buck is https://www.envyouscustoms.com/diagnostics/diagnostic-kits/aldl-cable/
its $80 and the software is easier to use than the others..plus your supporting a site sponsor...O2 sensor are pretty cheap and easy to do,if its the temp sensor normally the fan kicks in as well....

Was the CEL on when TPS was buggered ?
If the CEL is on, a fault is being logged.
You done the paperclip trick before ??

Mate no $$$$ required

Dont u know the paper clip trick? Takes 2 minutes you can do it right now free of charge. Any errors flash up on the dash

Gaskets?

Take your throttle body off and polish it till its original silver again

It chocks up with oil and gunk like boogers in your nose. It just needs a clean out
