Maybe this CASE Learn procedure will help?

Crank Relearn Instructions (With and Without an OBD Scanner/Reader)
Posted by Alex E. on 19 March 2016 04:29 PM
These Crank Relearn Instructions may not apply to all vehicles. But they're close to how it's done on most cars.

To perform the relearn, proceed as follows:

Connect a scanner to make sure there are no trouble codes stored in the computer’s memory.

If there is any power train trouble code other than P1336 (Crankshaft Position Variation not learned), the computer will disable the relearn function until the problem that caused the code has been eliminated.

Also, make sure that the engine coolant (check it when the engine is cold) and oil levels are at an acceptable level.

1. Set the parking brake and block the drive wheels. Make sure that the hood is closed.

2. Start the engine and make sure that the engine coolant temperature is at least 158 degrees F. (70 degrees C.)

3. Turn the engine off for at least 10 seconds.

4. Select the crankshaft position variation learn procedure (CASE Learn)on your scanner.

5. Make sure that the transmission is in Park. Start the engine.

6. Apply the brakes and hold the pedal firmly.

7. Follow the scanner instructions.



Remember: That you are going to increase the engine speed to approximately 3000 RPM, 4000 RPM, or 5150 RPM. That’s the variation learn fuel cutoff RPM (depending upon the engine), and that it’s important to release the throttle when the engine RPM starts to decrease as a result of the fuel cutoff going into effect. Failure to do such will result in over revving of the engine, causing possible engine damage.

8. Once the engine has returned to idle, check the status of Diagnostic trouble code P1336. If the scanner indicates that the CASE has been learned, the relearn procedure is now complete. If CASE has not been learned, check for the presence of other power train codes. If any exist, correct the problem, then repeat this procedure.



NOTE: If the Crankshaft Variation Relearn is not accessible through your scanner (some truck applications 1998 & later), perform the relearn in the following manner:

1. Turn off all of the accessories. With the Air temperature sensor and Coolant temperature within 5 degrees (Centigrade) of each other, start the engine and let it idle in Park or Neutral for two minutes.

2. Accelerate the vehicle to 55 mph at part throttle. Cruise at 55 mph for 8- 10 minutes until the engine reaches operating temperature.

3. Cruise at 55 mph for another 5-6 minutes.

4. Decelerate to 45 mph without using the brakes, and maintain 45 mph for 1 minute.

5. Perform 4 deceleration cycles, without using the brakes, of 25 seconds each where no specific speed is necessary. Returning to 45 mph for 15 seconds in between deceleration cycles.

6. Accelerate to 55 mph and cruise for 2 minutes.

7. Stop the vehicle and idle for 2 minutes with the brake applied and the transmission in Drive (automatic trans.) or Neutral (manual trans.) with the clutch depressed.

I may try this but I think my issue is that the jeep distributor is more that 100 deg out from where it should be.
I pulled it apart last night and moved the reluctor to where I think it should be.
After I've ran it for a few miles I'll check it.

So I got the O2 sensor hooked up today and on the short test run I made it really helped it. I'll be driving it about 60 miles tomorrow, so we'll see how it does.
I'm running one O2 with it hooked to the input to both bank 1 sensor 1 and bank 2 sensor 1. I'm using bank 1 sensor 1 12v to heat it. I turned the DTC off for the other O2.
I've also got the fans running off the computer.

I think the answer is even more simple. Put all 6 cylinders fuel injectors on Bank 1 and disable the codes for bank 2 sensors.

As for running a non computer auto trans. Flip the switch in the transmission tab to non computerized automatic and rewrite the entire file. Has worked on the numerous operating systems I have tried. Zero transmission related codes and you can even enable a single wire Park/Neutral switch.

Is it really that simple? So if I put all 6 cylinders on bank 1 it won't need input from bank 2 O2 sensors? I like it!!

Ok so I found the switch you're referring to. If I set it to non computerized automatic, what do I need to change? Everything under transmission?

[Thorwon]

Ok, I may have an issue with my computer. The "high speed cooling fan relay control" wire from the computer is not turning the fan on. It's wire # 33 in the green plug. It should ground the relay and turn the fan on at the set temp. When the engine gets to the set temp the relay clicks on and off repeatedly.
I've tried three different relays with the same result.

If I put my voltmeter on the wire it shows no voltage from battery neg to the wire. With battery pos to the wire it shows full battery voltage. Which is what it should show.
But when I hook the fan up it just clicks on and off repeatedly.

Do you think the circuit in the computer can be bad and give these symptoms?

Can you post the bin file you are using?

This is it.
