I will need to know the 8th digit of the VIN Number before I can give you the codes.



  • Turn ignition switch to OFF position
  • Locate Data Link Connector (DLC), see image below.
  • Jumper the A&B terminals(a paper clip or a jumper wire work ok)
  • Turn Ignition switch to ON position.
  • Count the flashes on the "CHECK ENGINE" or "SERVICE ENGINE" light.
  • FLASH, pause, FLASH, FLASH = code 12
  • NOTE: Some 94 & 95 models do not have the B terminal. In which case a scanner is required.
  • NOTE: Some 94 & 95 models that DO have the A & B terminals still require a scanner.
  • All vehicles after 96 are OBDII,and require a scanner to access them.
this is what you asked for but I agree with Corvette64 in that its probably in the fuel. the computers just don't give that much trouble anymore.
