Hi all, I have a 2002 Z track car that went into limp mode on track after driving it track style....hard. Anyhow, I got several DTC codes pictured below.
My question is for the experts, which I am not, I hooked up my Tech2 and got some TPP and APP sensor voltage readings with key ON, Eng OFF (2) and eng ON(2).
You think these voltage readings would cause a limp mode? THX Brian.
