It's really simple looking to do. And from what I read, make sure you in Metric Mode. Did this yesterday. Now you'll see everything active. Rev the motor and BAM, your done. Oh wow I didn't think this worked either for the longest time. Just connect the scanner with the lightning bolt, don't hit the play button.
A lot of VCM controls only work this way. When it hits the fuel cut, let off the gas and let it come down to idle. Shut the car off for at least 15 seconds to register the case learn. Put the vehicle into park auto or neutral manual. Turn the vehicle off. Apply the parking brake. Press the brake pedal. Keep the brake pedal depressed during the entire procedure.
Press Begin. Gradually rev the vehicle to fuel cutoff around RPM's over a period of about 4 seconds. When fuel cuts out, immediately release the throttle. Allow the engine to come back to an idle. Turn the ignition off for at least 15 seconds. This step is required for the VCM to store the newly learned configuration. Last edited: Dec 12, Reactions: threefiveleven. TJBaker57 Guru.

With the P if I were in your shoes I would recheck my work and ALL the related wiring of the crankshaft position sensor. Also the 5 volt reference circuits since these are mentioned in the descriptor for the P What was the impetus for replacing these 2 sensors to begin with?

With this code, you won't be able to do the CASE relearn. It has to be running. The P code specifically says it's a problem with the circuit and would set even before trying to start it.
Since you replaced the sensor, then it's something upstream in the wiring. If you have manuals check the ones in my signature , look up the schematics and start checking continuity on each wire end to end from the CKP sensor. Needing a CASE relearn would not prevent it from starting. Not having a crank signal would. Reactions: Mektek , Reprise and Mounce. TJBaker57 said:. Click to expand MRRSM said:. This is amazing! It looks like I need to go back over my work and make sure everything is good first, but then I'll post an APB!
I wish I could just get a real Tech2 of any kind, but right now none of it is in the budget at all. What are your resources now? Got a good multimeter amd know how to use it? Biggest obstacle is finding time. I only have a few hours here and there to mess with it. For now I just need the freaking thing to run. Reactions: threefiveleven , Reprise and Mounce. Jul 22, 2, One other thing, just to make sure There are two different ones for Gen 3 vs Gen 4 engines -- grey and black -- and they're not interchangeable although the connectors might be the same, since so many people warn about getting the right ones.
I replaced every sensor in my Gen III 6. As part of that, the new cam and the crank got turned a bunch of times while I put everything together, etc. Reactions: threefiveleven , Mooseman and TJBaker TollKeeper Platinum Donor.

If your vehicle has been parked outside for any length of time and not in running condition, then follow your Harness Wiring along from the Crank Sensor on the Lower Driver's aft side of the Block Trace along its length by using a Very Bright Flashlight and carefully feel everything there for the slightest damage. Here are some historical images of this problem The Owner eventually soaked Cotton Balls in Peppermint Oil and stuffed them in the crevasses and corners of the Engine Compartment to discourage the Vermin from Nesting.
Don't handle this stuff without using Gloves and a Mask Last edited: Dec 13, This makes research all the more significant. Quality Programmed Modules. Highway 71 Auto Parts. Set the parking brake and block the drive wheels. Make sure that the hood is closed. Start the engine and make sure that the engine coolant temperature is at least degrees F. Turn the engine off for at least 10 seconds. Make sure that the transmission is in Park. Start the engine. Apply the brakes and hold the pedal firmly.
Follow the scanner instructions.
