2014 Ram 2500 Bighorn 4x4, 6.4L 152k miles.

Remote-started truck yesterday morning (12°). Upon entry and turning "on", multiple lights illuminated on dash:
Check Engine,
Elect Stability Control,
flashing TPS (red lightning), and
messages "Service Electronic Braking System" and "Service Electronic Throttle Control".
Drove to dealer (no overdrive), they think its the TPS, have one on order.
Shows the following codes:
P0123 & P0222 (TPS)
P0108 (Mnfld Air Press)
P0198 & P0523 (Eng Oil Temp)
P0113 (Intake Air Temp)
P0118 (Eng Coolant Temp)
P04D1 (EGR)
Most seem to be a high voltage issue.
Anyone have ideas on what would throw all of these codes at once?

Have a feeling the expensive TPS may not be the real issue here... maybe wiring or common computer or?

Thanks in advance!
Walt

RESOLVED: dealership replaced MAP sensor, which resolved all issues (so far). Part was ~$50, labor ~ $130. Interestingly, service rep said they had just had an exactly similar issue two weeks prior with another '14 Ram 2500...
