After market parts are usually rebuilt parts vs OEMs are suppose to be new and made for the car specifically.

    The after market parts have a warranty. I have used them without much trouble in the past. If the sensor works through the warranty time it will probably last a long time. Those air flow sensors usually last a long time anyhow. There is a special metal screen the air passes through that sends the info to the computer. I would save the $500 difference if it were me. It will probably last the life of the car if you trade once in while. Darrell Sorenson

Have the fault codes read. Replace the faulty units with
genuine one because most aftermarket units are not set for OEM cpu units and are not completely compatible.. Check for mass air flow sensor fault.

Did you also replace your fuel filter? They are usually the reason that fuel pumps go out to begin with. Restrictive flow causes the pump to work to hard to deliver fuel. Also, check/replace plugs, air filter, coils (if distributor-less motor). Monitor your consumption over several tanks from various stations to get a true consistent reading.
I'm assuming you used an OEM pump, and not an aftermarket pump. Sometimes the aftermarkets will run a little different than the OEM and could cause extra fuel consumption. Good Luck

I have a1997 grand pri the gas mileage dropped from 28mpg to 16. throws code p0102? any ideas?


PO102 indicates a problem with the Mass Air Flow Sensor. Aftermarket air filters that require frequent oil to be applied to them can coat the sensor wire.
The most common issue, or starting point is to inspect the air induction tube for any leaks between the sensor and engine throttle body. You failed to mention what engine.
Cleaning the mass air flow sensor wire may be all you need. Good luck

I have a 2001 eddie bauer expedition and I am trying to replace the oxygen sensors myself if the cost is worth it


I work for BOSCH and the operator of the line which makes these sensors. A tip for you to save even more money. Don't worry about buying the OEM, the aftermarket is the same, just looks a little different, these are tested the same, have the same inside components. These are tested the same and actually have better elements in the sensor. These are very easy to change except the driver front. There is a special wrench you can buy to do this with and it makes it alot easier. Just ask about it when going to purchase. It takes 20 minutes and you're done. The sensors for oem are $75-100 each x (4). Aftermarket $45-65 each

How do i know what O2 sensors to order, there are several on my 2002 ford expedition V8/5.4ltr. engine? The diagnostic machine can no longer be used to tell which sensor is down due to my cigarette lighter...


Hi, I work for Bosch and I run the line that makes the sensors. I have replaced the mine in a 2001 expedition. It's fairly easy, except the driver front. When you go buy your sensor, buy the aftermarket. It has been tested on the line just as the OEM and passed with the same test. The sensors have the exact same components inside the sensor. The auto store will tell you different and so will the shop. The only difference is: when we assemble the OEM, it usually has the OEM marked on it such as Ford, GM, VW and so on. It seems like a long paragraph but I want you and anyone else to understand. However the top of the sensor may look different than the OEM, but that has nothing to do with the function of it. We make what is called LSF which is what yours will probably take. It should have the # marked on it: 0258986602 big aftermarket. This is sold at Advance. Auto Zone. Trust me friend, there's no difference in the OEM and Aftermarket. I wish I knew this when I needed them. Also the OEM is $70-$140+. Aftermarket $35-50. The lighter should not have anything to do with having it checked. Go to Advance, have them do a free check and then buy you sensor while your there. Tip: you may know this but, usually the code for your keypad entry is located under the dash, below the steering wheel. It is usually on a white sticker. It don't state that it is your code but it should be 5 numbers, and this is the master code even if you have changed it to your personal code. Also the **** you here about, we can't make an extra key unless you have 2 extras at the dealership, that is bull. When I bought mine it came with one key and no key fob. I had 2 extra keys made and a fob programmed within 10 min. We have a guy here that is awesome. He does it for the dealerships around here. Sorry for the long paragraph, just want to pass on info for the people that need it.

I have a 95 Trans Am myself, with a worked 383 lt1 with full bolt ons. etc Your using the factory tune with that setup? While the check engine light might not be on because of the factory tune i would strongly suggest at the least, getting a mail order tune, and if you can, a dyno tune. You're not seeing the full potential of your setup the way it is now. Are you using an aftermarket mass air flow sensor? The stock mass air flow sensor flows plenty for most setups. Aftermarket sensors can cause driveability issues and many suggest staying away from them.
Are you able to scan the computer to retrieve the codes? It's impossible to diagnose the check engine light without knowing why it's on.

This is almost always caused by a failing mass air flow sensor. If you had it replaced with aftermarket you may want to replace with oem to avoild problems. Thanks P0171 Fuel System Too Lean (Bank 1)Possible Causes Setting Conditions Base engine "mechanical" fault affecting one or more cylinders Check for air leaks after the MAF sensor Check for air leaks in the Air Induction system (e.g., in the intake manifold) Check for air leaks in the exhaust manifold and in the exhaust pipes Exhaust leaks located in front of the AFS or HO2S location Fuel control sensor is out of calibration (e.g., ECT, IAT or MAP) Fuel delivery system supplying too little fuel during cruise or idle periods (e.g., faulty fuel pump or dirty, restricted fuel filter) Fuel injector (one or more) dirty or pressure regulator has failed HO2S has failed (it may be contaminated with fuel, silicone or water) Vehicle driven low on fuel or until it ran out of fuel

Poor idle, power loss off idle then takes off if you give it more throttle like a quarter more pedal, engine code says bank 2 is to lean


You need a new MAF (mass air flow sensor or air flow meter as its called). and you will also need a new air filter, since you most likely used aftermarket one and that's what killed that MAF sensor/meter. Aftermarket air filters dont sit right in the box and are not oil soaked, which helps to catch any debris and dirt coming into your engine. Replace you air filter with Nissan filter and install a new MAF/air flow meter. If your air box is dirty, clean that out too. MAF sensor will run you about $500 and the air filter about $17. Common problem on a Sentra if you are not using Nissan air filter.
