Trying to fix an 05 Dodge Grand Carvan SXT 3.8l. FWD w/sto and go. It's got an ABS code for the LR wheel speed sensor. I Ohmed the sensor but I can't find any specification for what the value should be. All the info I can find is for Checking voltage etc. Are these gen4 vans different how the ABS sensor works vs. Gen3? My dad had a bad ABS sensor on his 1999 Town and Country and I measured Ohms to find it was bad.

 

I look in the service manual for 2005. It doesn't show ohm resistance, but there was something for DC voltage. I'll post it,because i don't know if you already have it.
TEST ACTION APPLICABILITY
9 Turn the ignition off.
Remove the ABM harness strain relief to access wires.
Reconnect the ABM harness connector.
Turn the ignition on.
Measure the voltage between affected Wheel Speed Sensor 12 Volt Supply circuit and
ground.
Is the voltage above 10 volts?
All
Yes ! Go To 10
No ! Replace the Anti-Lock Brake Module in accordance with the
Service Information.
10 Turn the ignition off.
Remove the ABM harness strain relief to access wires.

yes, I have all that information. I guess I'm just use to the old style sensor where you measure resistance. I guess I'll just have to follow the directions I have.
