Check Engine Light 2003 Gs430

[hellom8]

Hi,

This morning the CEL came on. The car has no symptoms.

Is there a way to read the CEL codes with out a code reader?

My old Scooby had a couple of wires under the dash that you would connect and the CEL would flash the error code for you, just wondering if Lexus has something simular?

Cheers.

I'm not aware of any shortcuts for the codes. If you were closer you could've used my reader, but they are pretty cheap these days and well worth having in the toolbox.

[hellom8]

Thanks TigerFish.

Is it the obd2 fault code reader that I need?

Cheers.

Ian.

Yes that's what you will need, some seem to have compatability problems with Lexus/Toyota but a half decent one should do the job.

Once you have the codes repost with them.

[hellom8]

Thanks for the confirmation.

Cheers.

Ian.

The cheaper ones should work no problem on yours. It was 1999-2000 GS300's that wouldn't work. My 2001 GS430 works no bother on the cheaper ones, although they can trigger a vsc light to come on. The reset procedure I posted up a few days ago for that, if it does happen.

Got my code reader today.

Gave me one code.

P0135 $10 1/1 Generic

O2 Sensor Heater

Circuit Bank 1 Sensor

1

Freeze Frame

DTCFRZF - P0135

FUELSYS1 - CL

FUELSYS2 - CL

LOAD_PCT (%) - 22.00

ETC(oF) - 178

SHRTFT1(%) - -0.8

LONGFT1(%) - -9.4

SHRTFT(%) - 0.0

LONGFT2(%) - 7.0

RPM(/min) - 600

VSS(mph) - 0

LAT(of) - 46

The car is under warranty and senors are included so the garage will be taking a look at it.

Guessing they will put a new sensor on the car, this might also explain my below average mpgs.

Cheers.

Ian.

bit of a result if it is covered under warranty :hohoho:

As you predicted, the VSC lights have triggered. I found your pin diagram and instructions on another post so will give that a go.

Cheers.

Worked a treat, no more VSC lights.

Good stuff :)

Had the sensor replaced under warranty, garage said they billed the warranty company £140 for the job.

Anoying thing is after five miles the CEL came on again. Took the car back and the second senor has now gone, so this has to be replaced now.

Cheers.

Ian.

[TigerFish]

Typical!

[hellom8]

Turns out the senors are ok, its the control module thats triggering the CEL and it has to come from Japan.

Cheers

After serval visits to the garage it turns out it was a sensor on the other bank.
