I had the CE light come on and the code it threw was an o2 sensor. The pda i had hooked up to it said it was working fine.

So we cleared the code, but its back. I ordered a new one, but has anyone had this code?

P0133?

A guy with an '02 LC on another forum has that one after having done a LPG conversion - Toyota won't look at it since he's done the conversion and that's not their bag.

This is the latest information from that thread on the other forum:
From a 1998 FSM

P0133 - Heated Oxygen Sensor Circuit Slow Response (Bank 1 Sensor 1) - Response time for the heated oxygen sensor's voltage output to change from rich to lean, or from lean to rich, is 1.1 sec. or more during idling after the engine is warmed up (2 trip logic).

Bank one is the bank with cylinder #1 in it. Sensor #1 is the sensor closer to the engine body. (left side exhaust behind cats)

The FSM (DI-52) asks if there are any other codes being output? If not it says to replace the sensor.
The lean/rich connection does sound like it could be LPG conversion related but if it trips when running gas as well I would replace the sensor.


So it sounds like replacing the sensor is the right idea, but make sure you're changing out the right one.

What was the code you got?

If convenient, a visit a local Autozone to have the code rechecked.

yea i'll have to ask the guy the code, but i have a 4yr unlimited warranty. So i'm just letting them do whatever to make the light go off.

I was just curious if this was a common deal.
