Another note about the left front (passenger) ABS/TCS sensor wiring on GTP's with the chronic warped front plastic manifold cover oil leak (they tried to just get away with putting a fatter gasket ROFL) is that this oil crud leaks down onto the top of the passenger side axle/control arm/rail. This is also where a second ABS/TCS sensor extension-cable wire from the passenger front sensor connection to the main engine harness lays.
Over time oil accumulation there will cause corrosive salt and brake rotor grindings to adhere to the connector and wires and thus, with moisture, to eventually get into the back of both of the connector's (rather leaky and loose) rubber-grommet splash-seals. This will cause leakage in the insulation values and may make the passenger-wheel sensor signal drop off, the easiest solution is to clean it with high pressure water. It's just down below the passenger side radiator plumbing connections 10" towards the center, laying on the rail.
Again get your dealer to fix the fire hazard SC recall repair again and/or get under the car and clean the extension connector-backs off (use brake cleaner) and then seal them good with some silicone to prevent oil/salt/water penetration.
