JR Branche Posted September 24, 2022 Share Posted September 24, 2022 Basically just got my truck back after 2 weeks in service for the EGR valve. 3 days after purchase nonetheless. NOW I have codes P0483: Cooling fan rationality check malfunction and P0526: Cooling fan speed sensor circuit. Loss of cool A/C at low speed or stop but once over 50, A/C gets cold again. Anyone else deal with this? I will update after I take it to the dealer in the morning. Quote Link to comment Share on other sites More sharing options...
