Engine check light on Codes POO 38, P0058.
2007 Dodge Ram 1500 (Hemi).
I have 4 codes, 2 POO38, and 2 POO 58.
I bought the truck used from a dealer. It had no
converters on the exhaust system. The check engine light was on. Dealer installed new converters, and o2 sensors. Light still on. Dealer
said that after market converters on certain vehicles does not have the proper flow to turn the
check engine light off. If so, do i\I need the proper
converters or are the o2 sensors wrong also,
probably after market sensors also. I have been
driving the truck like this for about a year with no ill effects, but would like to turn the check engine light off. Can you help? Thanks, John

Those codes are for heater control circuits. Cats have nothing to do with that. Need to check the wiring for the O2 sensor heaters...... PCM thinks voltage is too high on them.... for whatever reason.
