SAE P0 Codes

DTC Table: SAE P0 Codes

NOTE:
- The DTC code overview is listed according to SAE or VAG code.
- Electronic Power Control "EPC" relevant Diagnostic Trouble Codes (DTCs) are indicated additionally by the Electronic Power Control (EPC) Warning Light -K132- in the instrument cluster.
- Explanation of the Malfunction types (e.g. "open circuit/short to ground"):
See scan tool operating instructions
- If components are indicated as faulty: First check the wiring and connectors to these components as well as the system Ground (GND) connections referring to Electrical Wiring Diagrams. If no malfunction can be located, replace component. This is particularly relevant if Diagnostic Trouble Codes (DTCs) are output as "occurring sporadically" (SP).
- Erase DTC memory after repairing malfunction and generate readiness code again Reading Diagnostic Trouble Codes Monitors, Trips, Drive Cycles and Readiness Codes.

VAG 1551 print out, e.g.:
16497 P0113 035 Intake Air Temperature (IAT) sensor -G42- Signal too high, Sporadic malfunction

Explanation:
- 16497 DTC code
- P0113 Additional DTC code
- 035 = Malfunction type as a number
- Intake Air Temperature (IAT) Sensor -G42- = faulty circuit or malfunction location
- Signal too high = Malfunction type as text
- Sporadic Diagnostic Trouble Codes (DTCs) = Diagnostic Trouble Codes (DTCs) that are not always present e.g. loose terminal

Explanation of SAE Diagnostic Trouble Codes (DTCs):
System type:
- Pxxxx = Diagnostic Trouble Codes (DTCs) for the drive

Standardized code:
- P0xxx = Defined Diagnostic Trouble Codes (DTCs) with standardized DTC text according to SAE
- P1xxx = Supplementary emissions relevant Diagnostic Trouble Codes (DTCs) provided by manufacturer
- P2xxx = Defined Diagnostic Trouble Codes (DTCs) with standardized DTC text according to SAE, as of model year 2000
- P3xxx = Supplementary emissions relevant Diagnostic Trouble Codes (DTCs) provided by manufacturer, as of model year 2000

System group:
- Px0xx = Fuel and air measurements and supplementary exhaust gas control
- Px1xx = Fuel and air measurements
- Px2xx = Fuel and air measurements
- Px3xx = Ignition system
- Px4xx = Supplementary exhaust gas control
- Px5xx = Speed and idling control
- Px6xx = Control module and output signals
- Px7xx = Transmission
- Px8xx = Transmission
- Px9xx = Control module, input and output signals
