1992 Ford Sierra Trouble Codes

[PetroleumJunkie412]

Ok, slapped the 1992 Sierra ECU in the harness to get some definitive trouble codes out of it. Ran a KOEO test when I got home. EEC spewed out the following:

67 Park/Neutral circuit fault - PNP
Transmission Manual Lever Position (MLP) sensor circuit - Transmissions
(M) Intermittent Park Neutral Position (PNP) sensor fault - PNP

85 2.3L T/C Automatic - 3/4-4/3 Shift solenoid - Transmissions
CANP solenoid (ALL 1989) - Solenoids
(M) 1.9L MFI - System has corrected rich condition - Fuel control

86 2.3L or 2.9L Truck - A4LD 3/4 shift solenoid - Transmissions
(M) 1.9L MFI - System has corrected lean condition - Fuel control

76 Vane Air Flow (VAF) did not respond to "goose" test - VAF

91 (R, M) System running lean - Fuel control
Transmission SS 1 circuit/solenoid problem - Transmissions

Ran wires to pin 52 and 53 on the EEC into a 33 ohm resistor and to the 12v source to try to simulate the 3/4 shift solenoid. No effect, apparently.

Any suggestions on how to simulate an auto trans on a manual truck??

Guessing I'm going to have to hook a can purge solenoid in there somewhere as well.

Also, why is the system looking for a VAF?

Well, this is a good start, save the VAF issue.

Still trying to figure out how to simulate an auto trans.

Also looks like I'll have to jumper my O2 across two pins.
