Does "PRESS CONTROL SOL DUTY " follow the reference data?
YES
▶ Fault is intermittent caused by poor contact in the sensor’s and/or TCM(PCM)’s connector or was repaired and
TCM(PCM) memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, cor-
rosion, contamination, deterioration or damage. Repair or replace as necessary and go to "Verification of vehicle
repair" procedure.
NO
▶ Go to "Terminal&connector inspection" procedure.
