Should I do both the forward and aft or just replace the 'suspected' bad one? This is due to the fact that O2 sensors are under the chassis where they are subject to punishment from road debris, and they are subjected to a lot of exhaust heat. If the oxygen in the exhaust gas decreases, the air-fuel ratio becomes Rich. If the P0132 trouble code is left on and unaddressed for an extended period of time, it can damage the catalytic converter. It is also important to make sure the oxygen sensor wrench is attached to the sensor properly to prevent stripping during the removal process. I've been having a problem with rough idle on the second start ie. If it is ahead of the catalytic converter, in between the puffs of exhaust gas flow the momentum will create little puffs of vacuum.
Wifes gona help me sat. If you have anything that you would like to add, please feel free to leave a comment below. . If the light comes on, even for a second, you know that you have a short circuit causing the P0138 trouble code. After you mentioned that it was the other way around I found the website that agrees with your statement. I cannot understand that one. P0132 trouble code definition 02 Sensor Circuit High Voltage Bank 1 Sensor 1 What the P0132 code means When the P0132 trouble code has been stored by the power control module, it is an indication of a problem with the 02 oxygen sensor.
If it's normal, you have an intermittent problem that isn't currently acting up. Will let you know how it turns out. The downstream sensor is especially susceptible to this problem Youtube. I had the fuel pump replaced about a month ago so I will have the mech check for any loose lines, or cracked fuel neck. They are presented in order somewhat of most to least likely to cause the problem. Not uncommon for O2 sensors when the sensor reading is the issue; they get progressively worse so for a while they just throw the codes occasionally, then the problem clears and the computer turns the light off again.
The heated oxygen sensor 1 signal is sent to the Engine Control Module. If I recall it was not something I was looking to do due to the difficulty getting to it. So I can listen for the noise, as with the speaker and mirror I will have with it as collage semester over in couple weeks. For example O2S11 is bank 1 sensor 1 and O2S22 is bank 2 sensor 2. The downstream sensor is especially susceptible to this problem Youtube.
If the same speaker is dead, look for a small black plastic box bolted to it. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. Over time, the good interval will shorten and eventually the light will stay on. That will help you narrow down the location of the problem. I guess I'll schedule a day for it and replace the O2 sensor. How serious is the P0138 code? O2 sensor wiring Here's the O2 sensor wiring for my 2000 Sport.
I dont know when the last owner had spark plugs changed so ill change them this weekend, could that set the code. The peak rich and lean voltages are continuously monitored. If you would like to contact your Concierge directly, please call 800 301-5729. The solution is here : Ford Explorer P0138 Possible Solution : The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing. From what I've read here it could be several things like the O2 itself, wiring, the catalytic, or dirty connections. Just wanted to throw out that suggestion.
The mirror problem is unusual. It would be very rare to have a shorted sensor, and really rare to have a new one also shorted and setting the same code, but if the wires will reach, you can switch the plugs between the left and right sensors, then erase the code and see if the same one comes back. Who leaves ratings and reviews? I started with the least expensive resolution I was given and changed the fuel filter. Elite Explorer members see practically no ads, can add their own profile photo, upload photo attachments in all forums, and Media Gallery, create more private Conversations, and more. How serious is the P0132 code? Can you tell by the readouts if a sensor is faulty? We also cover the Ford Ranger, Explorer Sport Trac, Mercury Mountaineer, Lincoln Aviator, Mazda Navajo, Mazda Pickups, and the Aerostar. The operation should be nearly the same, except sensor 2 should have a lower O2 reading since the catalyst should burn off the excess fuel and oxygen. Bank 2: Sensor 1 O2S21 :.
The ideal air-fuel ratio occurs near the radical change from 1V to 0V. YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle. There it said that it is O2S21. The 1 Ford Explorer enthusiast resource on the Internet since 1996. We look forward to providing you with the ultra-premium experience that is a hallmark of Lincoln Black Label.
If the oxygen in the exhaust gas increases, the air-fuel ratio becomes Lean. But, like anything that causes the service engine soon light to come on it is a good idea to have it fixed as soon as possible. Those decisions won't be accurate or provide the lowest emissions and best fuel mileage but they will keep the engine running. I sense the Ex running a little bit more rough at idle than usual.
