Step
1 6) Disconnect the ECM coupler. Refer to "ECM Removal
and Installation in Section 1C (Page 1C-2)".
7) Insert the needle pointed probes to the lead wire coupler.
8) Check the continuity between the R wire and terminal
"11". Also, check the continuity between the G/Y wire
and terminal "26".

R and G/Y wire open, G/
Y wire shorted to the
ground.
• Check the vacuum
port for crack or
damage.
• Open or short circuit
in the G/Y wire.
• If vacuum hose and
wire are OK, replace
the AP sensor with a
new one. Refer to
"IAP Sensor Removal
and Installation in
Section 1C
