Try to reset the steering angle sensor (google it), otherwise they F'd up up the sensor and get ready to battle your SA again.
I think I'm going to pass on the airbag recall.....
...I get a 10k OHM resistance before applying my fix. When I add the resistor inline, I get 5k ohm...
The sensor you tried to "fix" was likely fine.
There are 2 sensors, full and empty. When immersed in DEF the sensor will be low resistance (a short). When not immersed the sensor should be 10k ohm.
You might want to check the resistance across the other 2 wires. If it reads "open" then install a 10k ohm resistor across those wires.
Here is how I did mine, somewhat of a step-by-step
1. Pull this panel off the bottom paying careful attention to how it overlaps or underlaps adjacent panels.
As mentioned, you will find passive tank under the drivers seat and to the left of the DPF. On the vertical surface of the rear of the tank, you will find the signal amplifier. Using a screwdriver, push catch to the side and push the amp upwards:
This gives you better access to both of the sensors wiring.
The catch to disconnect the sensors from the amp is where my screwdrive is. Gently pry that up and pull the gray plastic part out:
Press the gray plastic down to release the connector from the amp revealing the wires from each sensor. Black & Blue for the upper sensor and orange (red?) and yellow for the lower sensor. Ohm each pairs of wires to see which sensor has failed. My failed sensor was reading very sporadically.
I did not want to permanently modify the wiring (although it's a $60 harness) so I wanted to try something different. While testing, I broke a small cover off the male end of this connector, but that gave me an idea.
Bending the ends of the resistor wires like a fish hook, and coating them in dialectic grease, I stuffed the ends up into the faulty bays for the wires of the faulty harness and retested the ohms. After a successful reading, I stuffed the rest of the wire and the resister up into the connector.
Plugged it back in, cleared the codes using Carly and haven't had a problem for 500+ miles. Time will tell is my mod will hold, but so far I am pleased.
How many miles do you usually go before topping off the DEF because obviously the transfer pump will run since it believes the passive tank is always full?
