Step
3 1) Turn the ignition switch OFF.
2) Check the continuity between Y wire and ground.
Special tool
(A): 09900–25008 (Multi-circuit tester set)
EXCVA position sensor continuity
∞ Ω (Infinity)
3) If OK, then measure the EXCVA position sensor
resistance.
4) Connect the EXCVA position sensor coupler and set the
EXCVA to adjustment position. Refer to "EXCV Cable
Removal and Installation in Section 1K (Page 1K-6)".
5) Disconnect the EXCVA position sensor coupler and
