O2 Sensor Bank1 Sensor1

[surge]

My Check Engine light came on today so I hooked up my PC and it read:

--P0125 Insufficient Coolant Temperature for Closed Loop Fuel Control

--P1133 Sensor Circuit Slow Response (Bank 1 Sensor 1)

--P1135 Sensor Heater Circuit (Bank 1 Sensor 1)

I cleared the Check Engine light and about a few minutes later the following came up:

--P1130 O2 Sensor Circuit (Bank 1 Sensor 1)

I reset it again and a few minutes later the P1130 came back on.

In any case, it seems that the O2 sensor in Bank 1 Sensor 1 is bad.

Does anyone know the part # for this? and where is a good place to get this.

I found a few different O2 sensors. on Advance Auto Parts website:

Which one do I need? is Bank 1 Sensor 1 the Downstream or Upstream?

The Bosch is twice the money and has a 1 year Warranty and the Beck/Arnley has a Lifetime warranty for half the price.

sensor 1 bank 1 is the one at the back of the engine bay on the exhaust manifold

because you get a code it does no mean it is bad

get a motorvac to remove the carbon first

search this forum for the following code P1133 and you will find a wealth of good posts on this topic. I found my bank one on ebay for cheap. I would not suggest the aftermarket brands as the wiring does not match up.

Bank 1 is the one before the catalytic converter and underneath the vehicle. The bank 2 sensor is in front of the engine and can be seen from underneath the hood. I am almost certain both sensors are interchangeable. Your problem is the one underneath the vehicle. I am not certain if the sensor underneath the hood is called the bank 2.

I only needed the bank one to solve my problem. I am sure they want you to buy them both.
