Diagnostic Trouble Code (DTC) table: SAE P0 codes

NOTE:
- The DTC table is organized according to SAE and VAG diagnostic trouble codes.
- Electronic Power Control (EPC)-relevant malfunctions are also indicated by the MIL for electric accelerator mechanism (EPC warning lamp).
- Further information on the malfunction types (e.g. "Open/Short circuit to Ground)
- If components are designated as faulty: First check wiring and harness connectors for these components as well as Ground (GND) wiring for the system according to wiring diagram. Do not replace component unless there are no malfunctions found here. This is particularly valid when malfunctions are displayed as "sporadically occurring" (SP).
- Erase DTC memory after repairing malfunction.

Example printout on V.A.G1551 printer:
16497 P0113 035
Intake Air Temperature (IAT) sensor -G42-
Signal too large
sporadic malfunction

Explanation:
- P0113 additional DTC
- 16497 DTC
- 035 = malfunction type as number
- Intake Air Temperature (IAT) sensor -G42- = faulty circuit or malfunction location
- Signal too large = malfunction type as text
- sporadic malfunction = malfunction not always present, e.g. loose contact

Explanation of SAE codes:

System type:
- Pxxxx = Codes for the drive

Standard code:
- P0xxx = Codes defined according to SAE with fixed texts
- P1xxx = Additional codes supplied by manufacturer applicable to exhaust gas
- P2xxx = Codes defined according to SAE with fixed texts from model year 2000
- P3xxx = Additional codes supplied by manufacturer applicable to exhaust gas from model year 2000

System group:
- Px1xx = Fuel and air metering
- Px2xx = Fuel and air metering
- Px3xx = Ignition system
- Px4xx = Additional exhaust gas control
- Px5xx = Speed and idle control
- Px6xx = Control module and output signals
- Px7xx = Transmission
- Px8xx = Transmission
- Px9xx = Control modules, input and output signals
