Code listing for 87-88
Update: further info can be found by clicking here
I am not sure how to check the codes for these years without needing a "self-diagnosis checker". but here is a list of the codes.
Taken from a '88 factory workshop manual. Should be the same for 87-88
* turbo only
~ non turbo only
| Code# | Location Problem | Fail-safe function |
| 01 | Crank angle sensor | - |
| 02 | Air flow meter | Maintains basic signal at preset value |
| 03 | Water thermo sensor | maintains constant 80 degree C (176 F) |
| 04 | Intake air temp. sensor (air flow meter) | Maintains constant 20 degree C (68 F) |
| 05 | Oxygen (O2) sensor | Stops feedback correction |
| 06 | Throttle sensor | maintains constant 100% |
| 07~ | Boost sensor | Maintains constant -96mmHg (3.78 inHg) |
| 07* | Pressure sensor | Maintains constant 26.3 kPa (0.27kg/cm2, 3.82psi) |
| 09 | Atmospheric Pressure sensor | Maintains constant command of sea-level pressure |
| 12 | Coil with Igniter (trailing side) | Stops operation of trailing ignition system |
| 15~ | Intake air temp. sensor (dynamic chamber) | Maintains constant 20 degree C (68 F) |
| 15* | Intake air temp. sensor (intake air pipe) |
Maintains constant 20 degree C (68 F)

After you get the codes out and fix the problem (or even before) you have to reset the ECU to get rid of them.
Just disconnect the Neg battery terminal for more then 5 secs. If the codes come back then you didn't fix the problem.
