jps

hi wounder if someone can help me. have twin 2007 496 mag ho's after running hard for a minute or two and returning to idle both motors go in full guardian mode for a minute or two then return to normal operation . scan tool reads code 160 prt emct overheat and 179 stb emct overheat , when i scan the exhaust temp highest temp reading was 157 degrees could i have 4 bad sensors? or is there another explanation side note at idle getting 1.0 psi on one motor and .7 on the other and 10psi at 4000 rpm i believe the idle psi is low but exhaust temp sensor should trigger at 212 degrees any thoughts would be helpful thanks
