got a check egine light that didnt go away after 1-2 days so i got it scanned and the codes that came up are:
DTC:
P0134 O2 Sensor Circuit No Activity Detected Bank1 Sensor1
Manufacturer specific DTC Codes:
P1196 O2 Sensor Heater Circuit Bank1 Sensor1 Electrical Malfunction
P1392 Camshaft Position Sensor Bank2 Open Circuit short to B+

EDIT in the past i also had this code twice: P1196 MANUFACTURER CONTROL FUEL AIR METERING

 

1.8 or 2.8?

 

1999 2.8 auto

 

anyone know what the problem is? do i need a new O2 sensor?
edit.

* Camshaft Position Sensor Bank 2 (G163) faulty

could it also be that i need to replace my fuel filter? i read somewhere that a guy also had the P0134 code on his vw beetle and even after replacing the O2 sensors the check engine didnt go away and he was getting same codes, but after replacing the fuel filter it all stopped. for the P1392 one of the symptoms is a high fuel consumption, and i was thinking that it might also be connected with the fuel filter. what do you guys think, should i just go ahead and replace the fuel filter before getting a new o2 sensor?
