You will, in all probability have to get under the car to see it-you have one in front of the catalytic converter (each side) and one behind the cat (it doesn't really affect how the car runs, it only monitors the car efficency)-the O2 sensors are perpendicular to the exhaust pipe and have a 4-wire harness connected to it. they look like this:

Resolve or fix code 13


If you mean code P0013
It has something to do with eighter a problem with your camshaft pisition sensor or an 02 sensor bank 1 witch I think is more likely .
However bank 1 depending on how many 02 sensors you have in your vehicle witch you have not related to me could 1 of 2 or 3 sensor location eighter up stream or down stream bascily in front of the CAT or befind of it or the cam actuator

P0154


Your exhaust has four 02 sensors. Code PO154 refers to no activity at bank two, sensor one.,Typically 02 sensors are good for up to 100K miles, after that their performance declines. You can try removing the sensor and shake it closely, next to your ear ( listen for a rattle). If you hear a noise while you are shaking it. The 02 sensor is junk. The side that Cylinder #1 is on is "Bank one" the other side is "Bank Two". Sensor one refers to the upstream senor (the sensor located before the CAT. Sensor Two would refer to the "Down Stream" sensor. Which refers to the 02 sensor located after the CAT. I hope that helps. Please write back if you have more details or questions. Good luck.

Where is the 02 sensor located on an 1998 gmc vortec 6 cylinder?


On most of the GMC vehicles there is one located in the exhaust system before the catalytic converter and one after the catalytic converter.The one before the cat is your upstream sensor and the one after the cat is your down stream sensor.

I have 2008 toyoya tocoma truck only getting 13 mpg. the check engine light on, had it scope out said o2 sensor open, replced sensor had light cancel but came back on. still have problem


Are you sure you replaced the right 02 sensor? Some vehicles have up to 4 02 sensors and being the ones that have a seperated duel exhaust system. You will have an 02 sensor located upstream of the catalytic converter and one down stream of the converter so make sure you replaced the right on. If you used a scanner to tell you it was an 02 sensor it should have also told you bank one or bank two which translates to drivers side or passengers side will also tell you up stream or down stream.

Im confused my car is a toyota camry 6cyl not 4cyl and some say it has 4 o2 sensors and others say it has 2, hum, wich is it???? please help and also is there a site where it shows me like a diagram as to...


I have no diagram,but there is what they call upstream,and down stream locations.Upstream,is above the cat-converter,the down stream is below the cat-converter.This would be per-side.You have a left,and a right exhaust manifold.The exhaust pipes run from each manifold(left and right)to the catalytic converters.So you would have to have on the left side a up stream o2 sensor,above the catalytic converter.and a down stream o2 sensor,below the catalytic converter.this would also be on the right side also,this would be the total of four(4) o2 sensors.I hope this is helpful.
