ECM connectors.
3) If connection are OK, check that IMT valve circuit is as
follows.
• Wiring harness resistance of IMT valve control circuit
is less than 3 Ω.
• Insulation resistance of IMT valve control circuit is
infinity between IMT valve connector and vehicle body
ground.
• Insulation resistance of wire harness is infinity
between IMT valve control terminal and each other
terminal at IMT valve connector.
• Circuit voltage of IMT vacuum solenoid valve control
circuit is 0 – 1 V with ignition switch turned ON.
Are they in good condition?
3 IMT vacuum solenoid valve check
