Yes it does. Your computer can not calculate how much gas is needed for real and that will make it run rough to say the least. To change them is quite easy
just in front or just after the first bend of your exhaust.
unplug and unscrew.

Goto autozone/advance/pep boys and have them do a free OBD check with a scan tool. Most likely the O2 (oxygen) sensor(s).

I have a 2010 Chevy HHR I took it to Autozone to get check and they told me that it take o2 oxygen sensor heater condition code p0054?? And now my car runnig rough... Sad.....


Code 54 is for a problem with the heater circuit for the O2 sensor that is mounted after the catalytic converter. The problem could be the sensor or the wiring for the heater circuit in the sensor. The circuit would need to be tested.

Air filter, ECU, O2 sensor, bad EGR valve, or clogged cat converter.

Onboard diagnostic computer should be throwing codes. Autozone can check these free (as will other part stores).

Engine warning light up after starting the engine. Mileage is around 72,+++ km. is this common problem for suzuki swift model 2006?


This is a problem with one of the sensors. You can take the vehicle to Autozone and they will put it on their diagnostic computer for free. Then they will give you a code of what sensor is bad. It is probably going to be and Oxygen sensor or O2 sensor.

1998 WINDSTAR CSERVICE ENGINE SOON LIGHT IS ON


it's not likely a bad o2 sensor would cause it to run rough, but the catylitic converter, which is what the o2 sensor reads the flow of, would cause the car to idle and run rough.If you take it to an auto parts store to have a diagnostic test ran on it( most major parts stores will do this for free), thecodes it gets would help pin point it alot better.

My 2001 Ford Escape runs rough before it warms up. The check engine light has just come on. I assume it is an oxygen sensor. How do I replace it?


Well, fords are known for multiple O2 sensors... so I would have Autozone do a free diagnostic to see if

1. it really is an O2 sensor - and which one
2. eliminate the power feed to the injection/choke circuit.

CHECK ENGINE LIGHT IS ON AND SO IS THE AIR BAG LIGHT


I recommend taking your car to your local auto parts store like AutoZone. They will hook up their diagnostic computer free of charge and generate your error codes. They can also decode the codes and tell you what may be the proximate cause. Same thing the VW Dealer will do for a charge of $65 (but AutoZone is FREE). One of the codes probably relates to a bad seal on your gas cap (try removing, cleaning and replacing). One of the other codes might be indicative of a bad oxygen sensor. They cost $20+, so you want to be certain before you start a replacement. There are between 2-3 oxygen sensors on your car.

Sorry I couldn't be more descriptive.
