Perkins 1106D Industrial Engine Fault Codes

Sixteen codes appear in the Perkins service documentation extracted for this engine: 113, 117, 133, 142, 143, 144, 162, 169, 187, 197, 422, 439, 489, 516, 517 and 527. They cluster into cylinder and injection faults, timing sensor faults, sensor faults for coolant, oil, intake manifold and fuel rail, and a small group of electrical and parameter faults. Most carry the same blunt documented remedy, which is to service the engine rather than to attempt a field repair.

They are the cylinder faults, and the numbering is not intuitive: 117 is a Cylinder 1 Fault and 113 is a Cylinder 2 Fault. The higher number is the lower cylinder. Do not assume the code number tracks the cylinder number on this engine, and do not read code 113 off a 1104D-E44T table, where the same number means a No. 3 Injector Fault. The documented remedy for both is service.

Both are recorded as a Sensor Supply Voltage Fault, meaning one of the ECM's regulated supply rails to the engine sensors is out of specification, but the documented remedies differ. For 516 the instruction is to check the customer parameters or system parameters, while for 517 it is to schedule service. On the related 1104D-E44T the two are separated explicitly as a 5 Volt and an 8 Volt sensor DC power supply fault, which is a useful way to think about them here. Because these rails feed many sensors at once, a supply-rail code can raise several unrelated-looking sensor codes simultaneously; clear it first and re-read the list.

Code 422 is Intermittent Battery Power to ECM, and its documented remedy is to schedule service. It means the ECM saw its battery supply drop out or glitch while running, which is far more often a connection than a module: corroded or loose battery terminals, a chafed supply harness, a failing key switch, or a poor chassis ground. Code 439, Key Switch Fault, sits in the same electrical family and is worth checking alongside it.

Code 527 indicates a problem with the stored configuration values in the ECM rather than a physical failure, and the documented remedy is to check the customer parameters or system parameters. It typically appears after an ECM has been replaced or reflashed without the engine's parameters being programmed, or when a parameter has been set outside its allowed range. Nothing is broken mechanically; the engine needs its configuration written correctly before the code will clear.

Only partly, which makes cross-reading dangerous. Codes 133 Intake Manifold Temperature Sensor, 143 Timing Calibration, 197 Intake Manifold Pressure Sensor, 516, 517 and 527 carry the same meaning on both engines. But 113, 142, 144, 162 and 169 are all reused with different meanings: on the 1106D they are Cylinder 2, Pump Timing Sensor, Crank Timing Sensor, High Pressure Fuel Pump and Coolant Temperature Sensor faults respectively, while on the 1104D-E44T the same numbers mean No. 3 Injector, Secondary Engine Speed/Timing Sensor, Engine Operation Mode Selector Switch, Fuel Rail Pressure Valve Solenoid and Low Engine Coolant. Codes 117, 187, 422, 439 and 489 are documented only for the 1106D. Always read against the table for the engine you actually have.
