I'm not sure I will have to look ,I'm not getting codes. Also I'm unsure if the black/lt blue wire from the ECU to the sensors is supposed to carry 5 volts or if the is the wire the sensors respond to the ECU on . And I'm not sure about the low volt reading form the MAP sensor with the engine running I have 1.49 Volts the haynes manual says it sould be 2 volts and I found another reference for 1.5 volts .I have over 200,000 miles and I wanted to keep it going to 300,000 but I'm not going to keep throwing money at this issue.
