Contact the dealer or auto parts shop,such as autozone & find the reset procedure for the light. It comes on after 50k miles. If it comes back on replace the sensor,with a bosch one if available. 10% fuel mileage increase with that brand.

If you replace the o2 sensor and that is the problem of why the check engine light is on then yes it will reset on its own. this will take a few days of driving due to the computer running all its tests and all passing then light will shut off.
the code you have is for a bad o2 sensor or wiring to it, there are a couple of o2 sensors, this code is for the rear o2 sensor.

What fuse controls the O2 sensor heater? My engine light stays on. I went to autozone and had them run a diagnostic. It coded the fuse for the O2 sensor. I have previously changed the cat conv. and both O2...


There is no fuse for the heater on the o2 sensor if the heater isn't working its usually the o2 sensors bad. (even a new light bulb can come out of the box and not work) but it could be in the wiring.

Symptons o2 sensors


If your O2 sensors are malfunctioning, the main symptom would be that the Check Engine light will come on. On some vehicles, an O2 sensor circuit shorted to ground can cause a no-start problem.
If the "Check Engine" or "Service Engine Soon" light is on and there is a code for the O2 sensors, I would like to also advise you that many O2 sensor codes are not caused by the O2 sensors themselves. In many cases, the O2 sensors are only REPORTING the problem. for example, a code P0171 "Oxygen Sensor Lean" code is rarely ever caused by the O2 sensor. It is usually caused by a vacuum leak or a failed Mass Airflow sensor (MAF) or Manifold Absolute Pressure sensor (MAP) or a bad fuel injector. In these cases, repairing the real reason that the engine is running lean will fix the O2 Sensor code without replacing the O2 sensor.

My Service Engine Soon light came on about a year ago. I took it into the shop and got that problem fixed but the light stayed on, so I took it to advance auto parts and code tested it and it said that...


There are several types of O2 Sensor codes. There can be "Lean O2 Sensor" codes, "Rich O2 Sensor" codes, "O2 Sensor Slow Response" codes, or "O2sensor Heater Circuit" codes. The specific code that is being set changes the way you must go about diagnosing and repairing the problem. I will say however, that in about 80% of all the O2 Sensor code problems that I have had to diagnose, the O2 Sensor itself was NOT the problem. The O2 Sensor was only reporting a problem that was actually caused elsewhere. O2 Sensors are the final checkpoint in the engine management system. I think of them like a report card. If the O2 Sensors are right, the rest of the engine management system is right. If the O2 Sensors are not right, the rest of the engine management system is probably not right. (Except in the 20% of the cases where the problem is actually being caused by a failed O2 Sensor)

O2 light stays on


You're lucky you have an O2 sensor light, which most cars do not have.

Did you change both O2 sensors?

2000 windstar service light on


Your van has four o2 sensor's, the code should tell you which one is bad for exsample code should be like,
o2 sensor bank 1 sensor 1 or 2
o2 sensor bank 2 sensor 1 or 2

Also make sure you don't have a vacum leak.

My check engine light came on it said P2626


This is an O2 sensor failure with the sensor located in the manifold. The associated heater probably failed causing the sensor to fail.

Oxygen sensor replacement


It's something you can with simple tools, you have four O2 sensors. Your going to have to get the truck rescanned or if you have the DTC code, you can find out which O2 sensor has gone bad so you can replace it. Your going to have Two upstream O2 sensors on each exhaust bank, one O2 sensor before the Catalytic Converter, and the last one after the Catalytic Converter. Its like replacing a Spark plug and you can pick up the O2 sensor at any large Auto Parts store with a can of WD 40. Just unclip the wire leads to the O2 sensor and then with a O2 sensor socket or hint close end wrench and hammer, you can remove the O2 sensor from the exhaust pipe. Good luck and be safe.

Service Engine soon light on - diagnostic code says o2 sensor. What is an O2 sensor and is it hard to replace


You'll need to give us the specific code, in the format P0xxx. Just saying "O2 sensor" doesn't mean anything. It could be the heater circuit, fuse, o2 sensor itself, etc. Changing an O2 sensor isn't too hard but you may not need to replace it/them.

Please report back with the code or look it up at http://www.check-engine-light.com
