Question about Nissan Xterra

O2 sensor/check engine light

2006 Nissan Xterra keeps throwing code for bank1/sensor1. I replaced it, and the light came back on within an hour. The code was the same. I took sensor back to auto store thinking it was faulty. Replaced it yet again. Same thing. Same code...... not too sure where to go from here!

You are lucky they took it back. Did you use the proper wrench to install it and use the proper anti-seize lubrication? Check the wiring to it all the way that you can. IT would be best if you could check it all the way to the ECM. Do you remember what the code was?

B1S1 O2 sensor is threaded into your exhaust manifold, closest to the actual engine in the exhaust stream.

SOURCE: new 02 sensors fitted but same error codes came back

Check the wiring very carefully. A damaged wire can give he same code. Be sure there are no exhaust leaks.

It is a good idea if replacing one 02 Sensor to replace all of them at the same time. Location is- they screw into the exhaust pipes below the exhaust manifolds and before the muffler.( Very hard to miss them ). Make sure you have the codes cleared from the on board computers memory after repairs are finished. Good Luck and have a good XMASS,

SOURCE: I have a 2007 Nissan Xterra. Check engine light

if you have an O2 sensor faliure you will have a code for it. in fact youe exterra doesnt have O2 sensors. it has A/F sensor or "air/fuel sensor" if it went bad, than you will have a code for that sensor. What is the code number that you have?? need to start there.

Check engine light and T/C light come on. Machanic changed Bank1 Sensor1. Lights stayed of for a very short time less than 15 miles, both came back on. Machanic checked it with computer, no good answe


I doubt the code said to replace the O2 sensor. It probably said there was an issue with the data it was sending to the computer.
Sometimes the sensor is faulty, and sometimes there is a problem with the fuel system.
The O2 sensors give the computer data it uses to adjust fuel mixture.
If you can get the actual trouble code or codes we can advise.

Hi, I have a 96 Jeep Cherokee with straight 6 cyclinder engine.The check engine lights on and Itook get to be put on a machine and the codes readed P0132,P0135,P0300,P0301,and P0420. Could you tell me


p132+ an O2 sensor reading is high bank1,sensor1, p135=O2 Heater circuit is bad, bank1,sensor1.

P300= Random misfires, p301 misfire cylinder1.p302 misfire cylinder2

p420 Bank1 Catalytic converter efficiency failing

What this means is that the Bank1 O2 sensor is either bad or the wiring to it is defective. Check for heat burnthrough on wires. The misfires started randomly and now pinpoint to cylinders 1 and 2.

The Catalytic converter failing because the misfires are clogging it. This can self correct once the cylinders stop misfiring.

Which messed up first is where you start solving this. Replace the O2 sensor, it is fouled out on Bank1. The heater circuit(p135) just makes it work faster and has little effect once you are underway. But high resistence in the O2(p132) means it is coated and ineffective.

There is a problem with firing #1 and #2 sparkplug. Probably the cause for the Catalytic converter plugging. A cracked coil, plug wires, sparkplugs are some causes as well as dirty fuel injectors on those 2 cylinders.

It is a cause and effect situation where 1 part fails and damages another. You need to fix the source of the problem or you will repeat th damage.

How to fix a 2002 dodge durango with p0051,p0136,p0031 codes


All 3 of these Codes have to do with the O2 devices. Some are saying the heating elements are returning low signals. These elements are built inside the O2 sensors and are designed to make your vehicle get out of "rich" mode faster.

Bank2 sensor1, Bank1 sensor1, Bank1 sensor2. Check your connections and the wiring leading to these parts.

You may need to replace these O2 sensors if the wires are good.

Engine fault codes: P1684 P0135 P0456


Hi the p1684 means the battery has been disconnected within the last 50 starts, the P0135 is Oxygen O2 Sensor Heater Circuit Malfunction (Bank1, Sensor1), you may have notived an increase in fuel consumption. and the P0456 code means evaporated emissions system -small leak detected the causes could be either A small leak in any of the EVAP hoses or fuel tank hoses, a small leak in the purge valve or vent valve or the EVAP Canister may be leaking
Hope this helps

My 96 Chevy Blazer 4X4 failed echeck, due to codes: P0132(bank1, sensor1), P0135(bank1, sensor1), and P0143(bank1, sensor 3). All are O2 sensor codes. What sensors need replaced, and where are they...


Some of your O2 sensors are before the catalytic converter and some are after, based on your description. I've seen some cars that had to have all of the O2 sensors replaced when the exhaust system was replaced.

O2 sensors need a special socket to remove, and are best done when the exhaust is hot, and, also, antiseize compound should be used on the threads with the new O2 sensors.

Be prepared to have an exhaust technician change them out for you in order to get it passed the eCheck.

Good luck on this repair.

Bank1 refers to the driver's side of the engine, so follow the manifold from the engine back towards the catalytic converter, sensor1 will be before the cat and sensor2 will be after the catalytic converter.
