Perkins generator controller shows E015 and indicates intake air temperature high

Safety: Ensure adequate ventilation in the generator room to avoid buildup of exhaust gases.

• Inspect air filter: Remove the air filter element from the housing. If heavily soiled or collapsed, replace with a genuine Perkins air filter element.
• Check room ventilation: Confirm that inlet and outlet louvers are unobstructed and that any ventilation fans are operating correctly.
• Sensor check: Locate the intake air temperature sensor (often in the intake manifold or air duct). Inspect wiring and connector. Compare controller reading with ambient temperature; large discrepancies suggest a faulty sensor.
• Exhaust routing: Ensure exhaust pipes and flexible joints are intact and not leaking hot gases into the intake area.
• Reset alarm: After addressing issues, clear E015 and run the generator while monitoring intake temperature.
