Code P0633 off and on
Code p0633 (Sentry key immobilizer Module) secret key not stored not stored in PCM.
(I owned this truck for 7 years no problems same original 2 keys)
Was randomly driving home one day and the engine hiccuped and threw a code, got home turned it off and on ran fine but still engine light was on, by the next day of driving it turned off.
Week later randomly after no problems it just died at idle, it would turn back on and run for 1 second then die again.
Had it sitting 3 days ran the code it was P0633, started it and ran fine no lights or nothing, but now the doors won’t lock with key or in truck switches on both sides.
What could be the problem it runs fine besides the locks now, but I don’t wanna be stranded randomly. (Update, next day now the locks work on key and inside switches)
