Solved my engine surging and stalling issues. The price wa reasonable for a brand new sensor. If you are unsure about the MAF sensor being your problem, try disconnecting yours after starting the engine. Your engine will use default info to allow the car to run. If your driveability issues improve then you probably need a new MAF. This is what I did under advice from a mechanic and it worked like a charm.

    Comments about Dorman - TECHoice Mass Air Flow Sensor - Sensor Only:

    After using two units bought on the internet, I finally decided to spend the extra bucks and buy (hopefully) a better quality sensor. So far it has worked as advertised, cured the start/die problem when the engine was warmed up.

          I would have given this 5 stars if it had come with the tamper proof torx bit that was supposed to be included with the MAF sensor. The guy at the Advance store in VERMILION OH where I picked it up was kind enough to let me borrow one. This sensor was a snap to install and cured a perplexing problem. Works perfectly!

            Comments about Dorman - TECHoice Mass Air Flow Sensor - Sensor Only:

            2002 LeSabre 46K engine began to lurch/skip, and eventually service engine light came on. Advance scanned the code and it indicated MAF. My friend has a laptop with an interface to the OBD and we ruled out vacuum problems and other problems such as the o2. He also has a manifold pressure guage that also helped rule out vacuum leaks and pressure sensor problems. So, I purchased the MAF and installed. Luckily, that was it, the car runs out perfect now. The power is much more linear throughout the RPM range and smooth.

            The unit came with a torx tamper resistant bit to remove the maf. About 5 minutes to do it. Time will tell. This car already had the plenum gasket replaced early on as it is a common problem. I was a bit leary that this was the problem again.

                Comments about Dorman - TECHoice Mass Air Flow Sensor - Sensor Only:

                Used to replace the MAF on a '00 gm 3800 SC engine. Sensor is a frequency modulated signal. New sensor read about 600Hz with key on and engine off and around 3000Hz at low idle (~1000rpm). The old sensor's frequency was all over the place(900Hz to 4200Hz) with the key on and the engine off. I determined that with both an OBDII scantool and a DMM. The car wouldn't run at all. I was able to limp the car back home by unplugging the MAF sensor, making the ecu estimate the air flow instead of using the failed sensor in range value.

                    Had a maf sensor replaced by a mechanic two years ago trying to fix an engine lean code. It didn't fix it so we went about replacing almost every other sensor (map, intake temp sensor, crankshaft position sensor, iac valve, new valve gasket, new vacuum hose lines, oxygen sensors, new catalytic converter every year becaus they got plugged, etc) still couldn't get the engine lean code to go away. Finally the mechanic said just to drive it until it got worse. A year later it breaks down and the code says maf sensor. I bought this one and put it on myself and the lean code went away right away. Think I had a faulty one the first time

                              2002 buick lesabere, wife thought transmission was going out . After driving a awile I noticed some hesitation after stopping. So at next stop trounced on it ahd it about jerked me out of my seat. So got it home and disconnected the electrical plug to mass air flow sensor and took it down the road ,no hesitation. I then got it home and reconnected the plug and took the handle of a screwdriver and tapped on sensor which made engine hesitate verifing sensor was shorted. Bought the new sensor, replaced in about 5 min. car runs perfect. You will need a set of tamper proof torx socket which I picked up for $34 bucks. Alot cheaper than paying someone else, plus you will have the sockets for other jobs!

                                  Hi Jessica, good question! Yes, both Dorman and Cardone branded MAF sensors are made by the same company. There is no difference between these parts with the exception that they are sold under two different brand names. This is a common occurrence with most of the OEM parts where the part will remain the same while differ in brand.
