Fault table: from V.A.G code 16486 / SAE P0 codes
Notes:
-
◆ The fault code overview is listed according to SAE or V.A.G code.
-
◆ Electronic accelerator "EPC" relevant faults are indicated additionally by the electronic accelerator warning lamp ("EPC warning lamp") in dash panel insert.
-
◆ Exhaust gas relevant faults are indicated additionally by the exhaust gas warning lamp in dash panel insert.
-
◆ Explanation of the fault types (e.g. "open circuit/short circuit to earth"):
=> Fault reader operating instructions
-
◆ If components are indicated as faulty:
First check the wiring and connectors to these components as well as the system earth connections according to current flow diagram. This is particularly relevant if faults are output as "occurring sporadically" (SP).
-
◆ Erase fault memory after rectifying fault
.
V.A.G 1551 print out, e.g.:
16497 P0113 035
Intake air temperature sender -G42
Signal too large
Sporadic fault
Explanation:
-
◆ 16497 = Fault code
-
◆ P0113 = Additional fault code
-
◆ 035 = Fault type as a number
-
◆ Intake air temperature sender -G42 = Faulty current path or incorrect location
-
◆ Signal too large = Fault type as text
-
◆ Sporadic faults = Faults that are not always present e.g. loose contact
