TESTING AND ADJUSTING STANDARD VALUE TABLE FOR ELECTRICAL PARTS 20-16 PC400, 450-6 Sys- tem Name of component Connector No. Inspection method Judgment table Measurement conditions Monitor Air cleaner clogging switch P11 (male) P12 (female) Continuity If the condition is as shown in the table below, it is normal Air cleaner normal Continuity Between P11 – P12 Air cleaner clogged No continuity 1) Start engine. 2) Disconnect P11, P12. Engine speed sensor E07 Measure resistance If the condition is within the range shown in the table below, it is normal Between (1) – (2) 500 – 1000 Ω Between (1),(2) – chassis Min. 1 MΩ 1) Turn starting switch OFF. 3) Disconnect connector.
Measure voltage Measure with AC range Between (1) – (2) 0.5 – 3.0 V 1) Start engine. 2) Insert T – adapter. Adjust 1) Screw in rotation sensor until it contacts ring gear, then turn back 1 ± 1/6 turns 2) It must work normally when adjusted as above. Water level switch P08 (male) Measure resistance If the condition is as shown in the table below, it is normal Above LOW level Max. 1 Ω in sub-tank Below LOW level Min. 1 MΩ in sub-tank 1) Turn starting switch OFF. 2) Disconnect connector P08. 3) Insert T – adapter into connector at sensor end. Engine oil level switch P05 (male) Measure resistance If the condition is as shown in the table below, it is normal Raise float Max.
