Hello, 2009 5.7 hemi with almost 200,000KM on it.
The truck started idling rough or driving really bad at low RPM. It vibrates badly. At high RPM it goes away and when it warms up it also goes away.
The codes thrown were;
P0300 - Multiple Cylinder Misfire
P2017 - Intake Manifold Runner...
Figured it out! Finally!! So I got my truck used and it was clearly worked on by some idiot. Somewhere, no clue where, in the harness, the wires for the sensor are swapped around it seems. I rotated the sensor out of it's connector and hooked it up reverse and it worked! My god.
2009 RAM 1500, 5.7
So the rear left wheel speed sensor is not working. ABS module just tells my scan tool that "Rear Left Wheel Sensor Circuit". C1020 is the code.
1. Replaced sensor, nothing
2. Inspected wires, nothing
3. Did a short test, they aren't shorting.
4. Put a large M ohm resistor...
