Remember Me?

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:.

I looked up where to find this and I see it is on the passenger side, near the starter. 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. I'm seeing other posts saying you have to take off the doghouse to access this Do I need to test anything before replacing or just go ahead and replace? If replacing, I watched a quick youTube video and the dude had a special tool to attach to his ratchet. Needed, not needed?

The other thing that happens if one sensor is lazy or slow, codigo p0155, then when the PCM makes a fuel codigo p0155 because one of the upstream sensors told it to, but the down stream sensor is slow in changing, The PCM may consider codigo p0155 the down stream sensor did not respond to the change and will flag it as bad where it may just be slow. Also dexonline I compared the old to the new, I noticed the new "shaft" was slightly smaller than the old added photo of what I'm talking about but this part says it is for my van, upstream right.

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.

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.

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. Now you get to figure how to get the breaker bar on the socket to get enough swing to break the sensor loose. Good to go right? Pick a time that works best for you and our mobile mechanics will bring the shop to you. Engine Code P Sign up. I have found alot of threads on O2 sensors and codes. Here are the screenshots. I've attached a screenshot of what the OBD was showing when I cranked it up. After visually inspecting the wiring, your mechanic will use the OBD-II scanner to review live data from the engine control module to check for any issues with the O2 sensor heater circuit. The engine must be run for two and a half minutes with the air conditioner on and rear defroster on.

I don't recall how many "drive cycles" must be completed without an error to clear the P but some of the codes require multiple "drive cycles" to clear. Much appreciated. Very soon. Here are the possible repair solutions to fix trouble code P Thread: Engine Code P Diagnosing the P code will require technical know-how of the O2 sensor heater circuit functions. OK, maybe I am going about this the wrong way. Alright so once done with all steps should I expect check engine light to shut off? The O2 sensor was replaced and both codes cleared.
