1) Disconnect connector from TP sensor
with ignition switch OFF.
2) Check for proper connection to TP sensor
at "P", "Gr" and "G / R" or "Or" wire termi-
nal.
3) If OK, then with ignition switch ON, check
voltage at each of "P" and "Gr" wire termi-
nals. See Fig. 2.
Is voltage about 4 – 6 V at each terminal?
