ACCIÓN CORRECTORA PRIMERA
COMPROBACIÓN
Correct other faults that may contribute to
852 (e.g. faults pertaining to Injectors,
MAP, IAT, Pre-Cat O2, Post Cat O2
sensor)
Look
for
leaks
in
converter, HEGO sensors; repair leaks.
Check all sensor connections (see fault 842
Medida correctoras).

Injector Problemas, e.g. leaking, defective
injector
Correct other faults that may contribute to
872 (e.g. faults pertaining to Injectors,
MAP, IAT, Pre-Cat O2, Post Cat O2
sensor)
Look
for
leaks
in
converter, HEGO sensors; repair leaks.
Check all sensor connections (see fault 842
Medida correctoras).
Check if O2 sensor installed before the
catalyst is shorted to GND or sensor GND.
O2 (signal) Pin 3 to SECM Pin B13
SECM (DRVG GND) Pins A16, B17
SECM (XDRG sensor GND) Pin B1
Check if O2 installed after the catalyst
sensor is shorted to GND or sensor GND.
O2 (signal) Pin 3 to SECM Pin B19
Possible sources: SECM (DRVG GND)
Pins A16, B17 and SECM (XDRG sensor

Check if O2 sensor installed before catalyst
is shorted to +5Vdc or battery.
