Codes vs Faults 2010 Dodge Ram
This 2010 truck came in with three fault codes active. Instead of walking you through the testing, let's just go right to what was causing each code to set.
Here they are: P0522, P1281 and P0456
P0522 was a leaking oil pressure sensor.
P2181 was a poor connection at the coolant temperature sensor.
P0456 was a bad gas cap seal.

Battery Drain Testing 2002 Dodge Ram
This one gets a quick charging system check while it is running and looks good.
I'll be disconnecting the battery for testing but want to keep the electrical system powered up so will connect the memory saver but first, just in case, I do a quick code scan.

Checking A/C on 1998 Dodge Ram 1500
"The air conditioner isn't working" was the complaint on this older truck. A look under the hood at the visible parts of the system and I could see the clutch cycle switch had been leaking. When refrigerant leaks from a system it not only emits the refrigerant gas but some of the refrigerant oil as well. So if you look for signs of oil seepage you can spot a leak without having to grab a leak detector or black light. In this case the only oil residue was below the cycle switch at the dryer. It looked like a small leak so I expected to find the system with a low charge but not empty. I connected the low pressure side to the recovery machine and did indeed have some refrigerant pressure.
Now with that pressure reading you can tell there is enough refrigerant in the system that the compressor should be able to engage. You can't tell if how much refrigerant is in there. If the system is low and the compressor is engaged then the low side should be lower than you would normally expect to see on a fully charged system. When I turned the A/C on, the low side did go lower than normal and the suction hose was only cooling at 58F. Which was only slightly below room temperature in the shop at the time.
