Diagnostic Trouble Code (DTC) Table: SAE P0 Codes
NOTE:
- The DTC table is organized according to SAE and VAG diagnostic trouble codes.
- EPC -relevant malfunctions are also indicated by the Electronic Power Control (EPC) warning lamp in the instrument cluster.
- Further information on malfunction types (e.g. "Open/Short circuit to Ground). See Operating instructions for Scan Tool (ST)
- 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 VAG1551 printer:
16497 P0113 035
Intake Air Temperature (IAT) sensor -G42-
Signal too large
sporadic malfunction
Explanation:
- 16497 - DTC
- P0113 - additional trouble code (only for USA at present)
- 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
