The firewall relay has a small 15 amp fuse, it was blown.

Only code that comes up is a p1689.

I read somewhere that there is a possibility it could be the crank shaft sensor, is that possible?

Guys I’m pretty sure this topic has come up so sorry if the question is redundant. 2000 Cummins was starting fine and also idleing fine, but if I gave it and throttle the engine would shake. Tried checking the pressure on the lift pump, 0, none at all. Figured it was a bad lp so I dropped the tank and swapped it for a new one. I bumped tested the new one and nothing. Now truck will not start. Checked my relay and swapped it out with the horn relay and truck still honks. Please help!!!

i will test the APPS this weekend, go over all my grounds again, and if the issue persists I will look into the Timbo apps

I have the same 2 codes, plus a P0122 on the dash odometer.

I drove the truck yesterday morning. It seems to run fine at first, but as the engine warms up it starts to buck and jerk as if it is slipping in and out of fear, but the code still comes up as the p0222

Guys I’m new to this, My truck (2000 ram Cummins) is throwing p0122 on the dash, and p0222 on the scam tool. Just changed and cleaned the battery terminals, also changed the tps, now I’m lost. I did the whole disconnected battery’s and when I turn it on the p0222 is still on. When I drive it, the truck jerks when I’m just cruising, if I stomp on the fuel it drives fine. WhT do y’all think It could be? Anything helps

Thank you guys so much!! I really love this truck I love how reliable it’s been just an issue that I wasn’t sure about. But thanks for the reassurance Thank you guys so much!!

Hi there guys names Rick, I’ve had my 2000 Dodge Ram 2500 for about 4 years now. Since I bought the truck the oil pressure is well above 40 pounds when I first turn truck on. After the truck temp gauge goes up the oil pressure drops below 40 at idle, if I give it some fuel oil pressure goes up. I saw a video of mopar1973man on YouTube explaining that it’s an electronic issue between the two sensors. Is there a fix for this? Thanks for any help in advance
