I apologize in advance for the lengthy post. I am having shift problems and can't find my exact symptoms with a solution and have followed everything I could find in the factory service manual. My shifter stopped working completely and then worked the next day. Now it has stopped again. I checked voltage and had the battery load tested. I have cleaned all the terminals and applied dielectric grease. Emergency shifter works fine, clutch has been adjusted, and the dash indicates the correct gear. I went through the flowchart in the service manual and identified the following issues.
1. Angle sensor - original sensor resistance was 4.66k, in specs. Calculations up and down were over .6 so I replaced based on the up readings being over .4. The new sensor has much different readings but I understand you cannot test it the same way. I get the same readings on the sensor and at the 22p terminal at the ECU.
2. I am not getting voltage at the angle sensor 3p terminal. The wire has continuity to the ECU terminal. I checked voltage from the corresponding pin on the ECU to ground and had zero. Based on this I replaced the ECU but it did not fix this issue. It did fix the problem I had with the neutral and reverse lights staying on regardless of gear position.
3. Gearshift switches have continuity but no voltage going to them.
4. Gear position switch readings don't make sense to me. I get a circuit in the right place for each position and have open circuits on all the others, but there are significant differences in resistance. 1st - 11.4 ohms, 2nd - 5 ohms, 3rd 102 ohms, 4th - 6.8 ohms, 5th - 15.1 ohms, R - 9.1 ohms
5. No continuity between 8p connector and 22p connector for the gear position switch.
The motor spins when removed and connected directly to battery. It does not spin if connected back to the harness. I appreciate any help for what to check next or where to fix. I already seem to have wasted about $400 on a new factory angle sensor and ECU.
