Default Advice on 02 sensor code: P0134

Hi i own an 02 cruiser but im a total novice when it comes to repairs on the engine but as i was quoted 220 by dealer to fit sensor i thought i would give it a go my self!
so could anyone please advise me, which 02 sensor i have to replace? And where it is located on the engine

the code from the dashboard display is: P0134 - 02 sensor 1/1 signal inactive (neither rich or lean condition is detected from the oxygen sensor 1/1 input).

i have read on this forum there are 2 one before cat and one after? each sensor is a different price from my supplier so i dont want to fit the wrong one!

any advice/pictures would be really helpful

many thanx

Gary

Gary,

Yours should be the UPSTREAM sensor. 1/2 would be the DOWNSTREAM sensor by the CAT.

Hi Gary. It's the sensor that is mounted in the exhaust manifold. Make sure you use anti-seize on the threads of the new sensor when you install it.

Gary,

Here's a picture of it looking down over the back of the engine.

I recently had problems with my '05 having no power when you get down on it. even starting off from a dead stop, it was almost like putting the gas pedal thru the floor just to make it move. In addition my gas mileage was suffering BIG TIME *13MPG in town* I spoke to several people that told me to check my oxygen sensor even tho my check engine light was not on. I had already done a tune up, checked all my fluids, and my air filter *all things effecting gas mileage*. when i removed the O2 sensor it was actually BUSTED. I was told that not all cars will throw codes for O2 sensor if it is not working properly. is this correct?

Not sure about all cars, but the PT sure has the fault codes for the 02 sensors....

P0030 HO2S Heater Control Circuit Bank 1 Sensor 1
P0031 HO2S Heater Circuit Low Voltage Bank 1 Sensor 1
P0032 HO2S Heater Circuit High Voltage Bank 1 Sensor 1
P0036 HO2S Heater Control Circuit Bank 1 Sensor 2
P0037 HO2S Heater Circuit Low Voltage Bank 1 Sensor 2
P0038 HO2S Heater Circuit High Voltage Bank 1 Sensor 2
P0050 HO2S Heater Circuit Bank 2 Sensor 1
P0051 HO2S Heater Circuit Low Voltage Bank 2 Sensor 1
P0052 HO2S Heater Circuit High Voltage Bank 2 Sensor 1
P0056 HO2S Heater Circuit Bank 2 Sensor 2
P0057 HO2S Heater Circuit Low Voltage Bank 2 Sensor 2
P0058 HO2S Heater Circuit High Voltage Bank 2 Sensor 2
P0130 HO2S Circuit Closed Loop (CL) Performance Bank 1 Sensor 1
P0131 HO2S Circuit Low Voltage Bank 1 Sensor 1
P0132 HO2S Circuit High Voltage Bank 1 Sensor 1
P0133 HO2S Slow Response Bank 1 Sensor 1
P0134 HO2S Circuit Insufficient Activity Bank 1 Sensor 1
P0135 HO2S Heater Performance Bank 1 Sensor 1
P0136 HO2S Circuit Bank 1 Sensor 2
P0137 HO2S Circuit Low Voltage Bank 1 Sensor 2
P0138 HO2S Circuit High Voltage Bank 1 Sensor 2
P0139 HO2S Slow Response Bank 1 Sensor 2
P0140 HO2S Circuit Insufficient Activity Bank 1 Sensor 2
P0141 HO2S Heater Performance Bank 1 Sensor 2
P0142 HO2S Circuit Bank 1 Sensor 3
P0143 HO2S Circuit Low Voltage Bank 1 Sensor 3
P0144 HO2S Circuit High Voltage Bank 1 Sensor 3
P0145 HO2S Circuit Bank 1 Sensor 2 Slow Response
P0146 HO2S Circuit Insufficient Activity Bank 1 Sensor 3
P0147 HO2S Heater Performance Bank 1 Sensor 3
P0150 HO2S Circuit Closed Loop (CL) Performance Bank 2 Sensor 1
P0150 HO2S Circuit Bank 2 Sensor 1
P0151 HO2S Circuit Low Voltage Bank 2 Sensor 1
P0152 HO2S Circuit High Voltage Bank 2 Sensor 1
P0153 HO2S Slow Response Bank 2 Sensor 1
P0154 HO2S Circuit Insufficient Activity Bank 2 Sensor 1
P0155 HO2S Heater Performance Bank 2 Sensor 1
P0156 HO2S Circuit Bank 2 Sensor 2
P0157 HO2S Circuit Low Voltage Bank 2 Sensor 2
P0158 HO2S Circuit High Voltage Bank 2 Sensor 2
P0159 HO2S Slow Response Bank 2 Sensor 2
P0160 HO2S Circuit Insufficient Activity Bank 2 Sensor 2
P0161 HO2S Heater Performance Bank 2 Sensor 2
P0162 HO2S Circuit Bank 2 Sensor 3
P0163 HO2S Circuit Bank 2 Sensor 3 Low Voltage
P0164 HO2S Circuit Bank 2 Sensor 3 High Voltage
P0165 HO2S Circuit Bank 2 Sensor 3 Slow Response
P0166 HO2S Circuit Bank 2 Sensor 3 No Activity Detected
P0167 HO2S Heater Circuit Bank 2 Sensor 3

So you would think one of these fault codes would show up if somethings wrong.

I was told a long time ago that the actual fault codes that show up on the PT all have something to do with emissions and nothing else and the 02 sensors definitely fall under the emissions.

Carey the information you were given sounds like it was from an "old" techie. Probably one of my instructors or professors? haha.

The OBDII access port was originally for emission diagnostic reporting. It even started here in the Golden state of California later adopted by congress as a mandatory on vehicles under the Clean Air Act in 1970. An on and on......

The OBDII ports from about mid 90's have much more diagnostic reporting analysis then strictly emission systems and components. Like being able to monitor parts of the chassis, body and accessory devices, as well as the diagnostic control network of the car. So I suppose you could call any deficiency in the performance of the running gear emissions related?

OK, thanks, for the update on that. I was told that by an ASE certified Tech who used to be on the forum but, like me, has been around awhile. I do know a heck of a lot of stuff that breaks or is no longer working is not covered by any fault codes and won't cause the engine light to come on. Many people have had problems where no code shows and they wonder why.
