The oxygen sensor heater circuit Bank 2 Sensor 1 is located in the exhaust manifold before the catalytic converter. This heated oxygen sensor also called an O2 sensor or AF sensor monitors the oxygen levels in the exhaust before it goes into the catalytic converter. Oxygen sensors use heater elements to help them reach operating temperature. The ECM will log engine code P when the heater element within the oxygen sensor heater circuit at Bank 2 Sensor 1 takes longer than usual to heat up. If left unresolved, a malfunctioning oxygen sensor heater circuit can lead to engine performance and drivability issues. Here are some early code P signs to keep an eye out for:. Ideally, you should avoid driving and have the issue rectified at the earliest possible. This is because the trouble code P means an imbalance in the fuel to oxygen ratio, resulting in high fuel consumption, poor engine performance, and other drivability issues. If left undiagnosed, it can lead to severe engine damage. Here are the usual suspects:. Diagnosing the P code will require technical know-how of the O2 sensor heater circuit functions. So, if you are unsure, you should have a reputable mechanic diagnose the issue. When diagnosing trouble code P, your mechanic should make sure they inspect all the components, including the harness connector, the heater element, and so on. They should also look for broken or bare wires leading to the oxygen sensor. Failure to do so could mean replacing a perfectly good O2 oxygen sensor.

If left unresolved, a malfunctioning oxygen sensor heater circuit can lead to engine performance and drivability issues.

Advertiser Disclosure. Heated oxygen sensors contain heating elements to help them get to operating temperature quickly in order to minimize the amount of time spent in open-loop operation A fixed rich mixture. With a P code, the first step is to get it properly diagnosed to figure out what is causing the malfunction in the oxygen sensor system. Using the live data function of the FIXD sensor and app allows you to read and analyze engine data to properly diagnose a P code. Many, if not most, shops will apply this diagnosis fee to any required repairs if you have them perform the repairs for you. From there, a shop will be able to give you an accurate estimate for repairs to fix your P code. When it comes to making repairs associated with the P code, one or more of the below repairs may be needed to solve the underlying issue. For each possible repair, the estimated cost of repair includes the cost of the relevant parts and the cost of labor required to make the repair. Complete diagnosis may require some specialized equipment beyond what the FIXD Sensor can provide, but the biggest challenge for this repair is that internal engine issues could be the root cause of this code.

It is caused by a failure in one of the oxygen sensors heated elements, specifically bank 2 sensor 1. The purpose of the heated element in the oxygen sensor is to quickly bring your O2 sensor up to normal operating temperature after the vehicle has been started. Typically, the only symptom of P is going to be the service engine soon light. It should not be considered a breakdown risk. 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. Here are the most common issues that cause the P code in the Ford Explorer. They are presented in order somewhat of most to least likely to cause the problem. It is possible to diagnose the P with a multimeter. If the light comes on, even for a second, you know that you have a short circuit causing the P trouble code. Good luck finding whatever caused it in your Ford Explorer.

Same issues with driver side to passenger side. They should also look for broken or bare wires leading to the oxygen sensor. Frustrated no doubt. Pick a time that works best for you and our mobile mechanics will bring the shop to you. Let off the accelerator pedal. Do I fork over a ton more money and get the AC Delco? Very soon. Yes, you can get the socket from your LAPS. Trying to get out of town this weekend. I'm seeing other posts saying you have to take off the doghouse to access this I can barely reach all the way up to be able to access the clip to undo it if I need to put in a new one.

The more electrical load you can apply the better. Here are the usual suspects: A malfunctioning O2 heater circuit Bank 2 Sensor 1 A faulty spark plug A malfunctioning engine coolant temperature sensor High O2 sensor heater element resistance A blown fuse connected to the O2 sensor heater circuit There are broken or bare wires leading to the oxygen sensor A damaged O2 sensor connector The car battery voltage is low The O2 heater element is faulty The O2 sensor heater circuit is open, shorted to voltage, or shorted to the ground The hose to the exhaust gas recirculation system module is disconnected. Do I clear the code and see what happens? Now you get to figure how to get the breaker bar on the socket to get enough swing to break the sensor loose. Insert Quotes Quotes Post Reply. Can I still drive? Replacing the sensor should clear it up. Needed, not needed? The other thing that happens if one sensor is lazy or slow, then when the PCM makes a fuel adjustment because one of the upstream sensors told it to, but the down stream sensor is slow in changing, The PCM may consider that the down stream sensor did not respond to the change and will flag it as bad where it may just be slow. The excess fuel then escapes into the exhaust manifold and eventually out of your tailpipe, resulting in black smoke or a rotten egg-like smell emanating from the exhaust.
