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.

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.

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.

Ian.

Worked a treat, no more VSC lights.

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.
