No other mass airflow sensor available gives you this much control. Engine running too rich or too lean? No problem!! Just whip out a screwdriver, give the calibration screw a twist and WHAM!!, problem solved. The sensor provides up to 30% more airflow than the standard OEM unit, and you don't have to tear out the screen! The Granatelli Motor Sports Adjustable Mass Airflow Sensors come equipped with a calibration screw builtright in. This unit is the only mass airflow sensor that features fully adjustable calibration, so high lift cams, big valves and larger intakes are no longer a tuning problem for performance enthusiasts. I apologize for the long post (trying to give as much info as i can up front) and I appreciate you taking the time to read this and thank you ahead of time for any insight or information you can provide me.If you have a highly modified 1985-1991 TPI Corvette, then this is the sensor for you. tried the taping MAF sensor test wiggling wires, feeling around all the wires in the engine compartment to try and reoccur the problem and havent had any luck. I also looked for vacuum leaks couldn't find anything.

I am basically not having much luck trying to locate where in the shop manual i need to go next. Also tried looking in the ignition section. I tried looking for a circuit diagram so i can find out where the ground is for the 339 circuit and am not having much luck. Now im not really sure where to go from here. Open ignition feed circuit to MAF sensor (i believe this is it) or Open ground circuit to MAF sensor. Measure volt between terminal C and chasis ground, should be B+ Heres a question, im assuming that means it should have a positive volt? If so, no it has like -.19 volts.Ĥ. Measure voltage between harness connector terminals B and C Should be B + Is it? Yes it was reading just shy over 5 volts.ģ. Connect voltmeter between term A and ground should read between 4-6volts, does it? It toke me a while but i did manage to get it to set eventually while sitting in the driveway.

And BOOM, happened again :smash: I have both of the shop service manuals for the car and followed the steps.

After replacing them the car ran great for a few days/trips. These are the only ones i am able to find on the car besides the messed up AIR one.

I also found 2 mounted on the drivers side of the radiator (these were replaced as well). I found 3 relays on the passenger side (somewhat near the windshield washer fluid fill) I replaced them all just in case lol. I was reading that it could possibly be the relay, I tried locating it on my car and it there is not one on the back firewall behind the battery. I have a new and the old MAF sensor ive tried them both and still the same problem.
#Corvette mass air flow sensor problems code#
(im 99% sure this has no connection to the issue as its been like this and driven fine with the code 28 for well over a year). I also have a code 29, which is the AIR pump circuit ( the relay for this is messed up and the fused is blown) Im from Florida so I dont have emissions to worry about so ive just left it. (the car will drive fine, until the problem occurs, then it will just go down hill from there and keep occuring). It could cut out again at the next light or 10 stops down the road. I can put it in neutral and it starts right back up and everything's fine. Randomly (usually at a stop light or while first moving, the car will cut out). Its throwing a code 48 (Mass Air Flow Sensor Circuit). Ive been having this "issue" and havent had the best of luck trying to solve the problem.
