Code 18 - SPOUT out or wiring fault - look for short to ground in SPOUT wiring going back to the computer.

Code 29 - Vehicle Speed Sensor (VSS) is an electronic sender mounted on the speedo pickup gear on the trans. It works the cruse control for both 5 speed and auto trans cars. On auto trans cars, it tells the computer to speed up the idle slightly as you slow down to a stop to keep the engine from stalling. Check to see if the electrical connector is plugged into it. Cost is under $30 and it is easy to replace.

You disconnected the VSS, that's why you got code 29.


Code 67 - clutch not depressed (5 speed) or car not in neutral or park (auto) or the A/C was on when you ran the test (it is supposed to be off). Possible neutral safety switch or wiring problem. You can generally ignore this code, since it has no effect on engine performance. The code will affect some of the engine running diagnostic tests the computer can do if requested.

Code 85 - CANP solenoid (ALL 1989) - Solenoids the Carbon Canister solenoid is inoperative. Check vacuum lines for leaks and cracks. Check electrical wiring for loose connections, damaged wiring and insulation. Check solenoid valve operation by applying 12 volts to the solenoid and blowing through it.
