Caterpillar Turbo Fault Codes

CAT fault code 102-00 generally relates to intake manifold pressure or boost pressure being above the expected range.

CAT fault code 102-01 generally indicates intake manifold pressure or boost pressure below the expected range.

CAT fault code 102-03 points to an intake manifold pressure or boost pressure sensor circuit voltage above normal.

CAT fault code 102-04 indicates intake manifold pressure or boost pressure sensor voltage below normal.

CAT fault code 102-07 indicates the intake manifold pressure or boost system is not responding properly.

CAT fault code 102-15 usually indicates intake manifold pressure or boost pressure above normal at a least-severe level.

CAT fault code 102-17 generally means intake manifold pressure or boost pressure is below normal at a least-severe level.

CAT fault code 102-18 indicates intake manifold pressure or boost pressure below normal at a moderate severity level.

CAT fault code 2629-03 is commonly associated with a turbocharger-related pressure or air-system sensor circuit voltage above normal.

CAT fault code 2629-04 generally points to a turbocharger or air-system pressure sensor circuit voltage below normal.

CAT fault code 2738-03 is typically related to a turbocharger, intake, or air-management sensor circuit voltage above normal.

CAT fault code 2738-04 usually indicates a turbocharger, intake, or air-management sensor circuit voltage below normal.
