Check Engine light?
I recently popped a check eng light while driving to work. I drove around with it on for a couple of days, while i was waiting for my AeroForce Tech gauge to come in. BTW, this gauge is great. Hooked it up and it shot out two codes: P0102 and P0440. Does anyone have any info about this and what is the fix?
P0102: Mass or Volume Air Flow Circuit Low Input
P0440: Evaporative Emission Control System Malfunction
2000 Mill Yellow C5, 6spd, 74500 miles
Thanks in advance!!!

Why do you need an aftermarket code reader??? There is one built in to your C5!
This is the absolute best C5 Code web site!!! It tells you how to read the DTC's and what they are!

Go to “technical data base” and then to “Corvette ECM Computer Codes”. Then select your year car. Read the instructions and then scroll down to the "READ MORE" window to view the code definitions.\
Here is another very good site:

Try cleaning your MAF sensing wires. You can use a good MAF spray or, I just use BRAKE PARTS CLEANER!
Just spray it on, let it evaporate and that should take care of it! MAKE SURE that the ducts betweem the MAF and the TB are sealed 100%.
The other code is most likely a dirty AIR system check valve. The on e for the drivers side is a snap to change. The other one is behind the head and will most likely require you to remove the intake to replace it. I used a spray and some compressed air to clean mine inplace and it was 100% effective!

Whats the condition of your battery??? A low battery can contribute to the column lock issue. Disconnect the battery, charge the battery and reconnect the battery. Clear any DTC Codes and see if you still have the problem/

I also have just been flashed with the P0440 code. The Evap system. What will this involve? Is it assumed the AIR pump is shot?
