2003 Ram 1500 5.7L Engine Multiple Fault Codes: P0441, P0183, P0585 — Cruise Control Not Working
My 2003 Ram 1500 with a 5.7L engine is showing three diagnostic trouble codes: P0441, P0183, and P0585. The cruise control system activates but fails to engage when I attempt to set it — it turns off immediately. I have already replaced the gas cap, but the issue persists. Any insights or solutions for these specific codes on this model would be greatly appreciated.
P0441: Indicates no flow detected in the EVAP system — points to a purge (LDP) valve issue. P0183: Fuel temperature sensor circuit malfunction. P0585: Cruise control system fault with a 1/2 correlation, suggesting possible sensor or wiring problem in the cruise control module.
