I have a perfect running 1996 es300 ,, I am getting a p0170 code ,, I cleaned the idle air valve and dont see any vacum leak's /?????

You are correct that bank one is on the same side as cyl 1 ( unfortunate for you, this is the hard one to reach0. I prefer bosch, and yes I buy the generic.

Make sure your connector is in good shape before ordering a replacement. I do not like crimp connectors, I prefer to solder and heatshrink the connection, it is more repliable. Finally, once the error is corrected, after so many drive cycles, it should clear itself, (I do not remember exactly how many).

Thank's I bought a Denso sensor , The color code chart was hard to understand but I figured it out , Toyota had black heater wires nad denso had white . The ground and sense wire's were different also . Thank's

I have a p0135 code bank 1 sensor 1 , I think that is on cyl 1 before cat. My question is ar all sensor's the same quality, I see sensors that the wires must be crimped , Generic and half the price, also dose the cel have to be reset or will it reset itself after the sensor is replace'd....

I have a 1995 check engine light where is on, Where is the connector and what type of reader is needed, I have a ocb II , Will that work , Also can I short somthing out and get it ...HELP,,,

Thank's

My abs light is on on my es300 1995.I shorted tc to e1 and took off the shunt and the first time I got a 32,35 ,then I tried again and got a 35.I cant clear it ,,,,,Can somone please t :cries: ell me what this means.

1995 es300 abs light on,can I use ocbII tester to find code.where is connector for code reader,can I isolate code to the failed sensor,

Yes, it is located on the back side of the evaporator (between the firewall and the evaporator). It is very difficult to access.

I had this valve replaced on our 94 ES in 2004. It cost about $450.00 at an independent auto air repair place. The Lexus dealer wanted around $700.

The system has worked great since that time.

Thanks ,I am going to attempt it ,The air is working now,but it will fail sooner or later,Thank's

The mid-90's ES models are notorious for expansion valve problems in their A/C systems. I don't know if a sticking expansion valve would cause your particular pressure differentials; however, it is the first thing I would check.

This has been discussed numerous times on this forum. Do a search.

Is it attached to the evaporator and is it hard to get out.

I think I have a clog in a/c .I have no presure on low side ,And there is about 160 Lbs on hi side with 3 , 13oz cans of refrig in system,I changed the reciever dryer,,,No help????
