Vehicle: 2015 Jeep Grand Cherokee. Have you ever had trouble with the Variable Valve Timing system on a newer Chrysler vehicle? There is a functional test available to help. In this Diagnostic Quick Tip, National Field Trainer Jason Gabrenas shows you how to perform the automatic system cleaning using a scan tool.
Variable valve timing systems on a lot of these newer vehicles have a lot of different components, cam gears, things like that.
And a lot of times they can get clogged either through lack of maintenance or a couple of other different reasons.
There's actually a scan tool function that you can go through and clean it on some newer vehicles so let's go through that process on this Jeep right now.
The tool is plugged in, the ignition's on, let's fire it up. The tool is going to automatically ID the vehicle for us. That beep says it's done.
Let's go into my scanner. There's my vehicle, then that's going to be under the Engine System. so we'll go in there, and then that'll actually be under Miscellaneous Functions on the second page.
This has an intake phaser so we'll go to the Intake Phaser 1 Cleaning Process. It says this function should be used to help clean dirt and debris from the oil control valves. That's what we want to do. We do have to have the vehicle running, so let's start it up right now.
Click continue. I'm going to go through the routine. You can hear the idle go up and down. Okay, that one's complete, and we'll go down to number two.
Same thing. It goes through and cleaning is complete. There we go. We're all done to automated tests and it cleaned out both those intake phasers. Pretty simple.
