DTC P0115 ENGINE COOLANT TEMPERATURE SENSOR (ECTS) (CIRCUIT); DTC Confirmation Procedure; Wiring Diagram

Wiring diagram ECM terminals shown are 71 (B/W) and 78 (R/G) — note: prior ECM Inspection Table 5 lists terminal 78 R/G as ECTS signal and 71 B/W as sensors' ground. The component-description note on EF & EC-7086 references 'ECM terminal 70' for ECTS measurement which conflicts; captured here as the wiring diagram shows.
