Question about 1994 Chevrolet Corvette
94 Vette ASR Code keeps coming on How do I Fix Problem?
SOURCE: fuel sensor gauge
you will need to replace the fuel level sensor.(sending unit) it is in the tank and is hooked to the fuel pump. you can buy seperatly from pump. you may finf it easier to remove the bed if you have some help. it is six or eight bolts and harness unplugs then you can get right to it.

SOURCE: Check engine Light
The P0455 indicates you have a gross vacuum leak in the EVAP system.
Start at the engine and the vacuum purge valve, start checking the vacuum hoses and lines all the way back to the EVAP canister near the gas tank. Make sure no hose or lines are cracked / disconnected.
If all looks OK, let me know and we will proceed from there. Below is a schematic of the EVAP system for reference.
Good luck and let me know.

yes they can but unlikely-more likely a bad over voltage relay(powers up idle speed computer) or wire harness-your vehicle is probably a hfm type fuel injection they changed from lh that year. find out if it is lh check the fuses in the base module located in the passenger side of the engine compartment under a cover held in by 4mm allen head bolts-alot of times these control units have intermittent contact with there connectors. asr stands for acceleration slip regulation-both isc and asr communicate via can system to monitor throttle position- ea isc cc-idle speed cruise control and electronic actuater(throttle)-hopefully i have helped

Most likely cause is the 'stop lamp switch'
It is a electric switch located on the brake pedal inside the car, about half way up on the brake pedal.
Pretty cheap too, I think the switch is only like $25 bucks.
2 connectors on the switch and then it turns out.
hope that helps

The light should come on for a few seconds as a test. If it then goes off this is normal. If however it stays on then the ASR (Acceleration Slip Regulation) has a problem. This is a very complex system that uses the anti-lock brake, cruise control, idles speed control, to prevent wheel slip. It can even apply the rear brakes individually and control the throttle. This system has no self diagnosis, and therefore is very difficult to repair for someone not familiar with this system. I suggest you take this car to a mechanic or a Mercedes dealer who has experience with this system.
