You need service repair info. for diagnostic testing for code co545.
Circuit/System Description
The power steering control module (PSCM) continuously monitors the torque sensor input and output shaft sine wave frequency signals. As the steering wheel is turned and torsional twist is applied to the steering column shaft, the torque sensors input and output shaft sine wave frequency signals are processed by the PSCM to detect and calculate the steering torque.
Conditions for Setting the DTC
The PSCM detects open, short to ground or short between any of the torque sensor circuits.
Actions Taken When DTC Sets
• DTC C0545 is stored in memory.
• The driver information center (DIC) displays the SERVICE POWER STEERING warning message.
• No steering assist.
TP reading ? spell it out !That fuse powers EPS - electronic power steering control module ! Have it checked for DTC'S - diagnostic trouble codes , dealer
It means the PCM has seen a problem with your engine running and has reduced the power for your safety. You need to bring your vehicle in to someone with a scan tool to read your trouble codes so they can look in the right direction to repair the non-performing part.
This was available on several different makes and model cars. If you select the 'power' position, the car will rev a bit higher before it shifts, kind or a ' performance' setting. The 'comfort' position will shift earlier, and is probably a bit more fuel efficient. The power mode would be good for driving in a hilly terrain area, the comfort on flat terrain and the highway.
If you have a selec-track NP229 transfer case, likely the viscuous coupler if failing that would account for the shaking at speed and no motion on hill at 2k rpms. The single wheel spinning at the rear may be that you don't have a posi differential but an open rear, or, the clutches are stuck. (can often be released by changing lube, adding posi additive and then making tight circles in both directions or tight figure 8"s) If engine is always idling at 2K you may have a vacuum leak somewhere. That can cause other problems with any vacuum operated controls elsewhere in the car.
