ya thats what i was wondering. it could be that broken wire to the oxygen sensor. the tps sensor is within spec that the manual gives. ecu temp sensor is brand new and test out ok. it has to be the bad oxygen sensor wire. what causes the cel to not come on when i have codes but does only shows the engine light when the diag box is jumped??? Appreciate the help cre and everyone helping
