Ok I had the CEL checked I got 3 codes
p1647
P0057 HO2S Heater control Circuit(Bank 2 Sensor 2)
P1000

I found a blown fuse F42 Will the fuse throw this code?
Will it clear itself?

Thanks for any help

 

A blown fuse will throw the code but I don't think they will clear themselves. You need to connect an OBD scanner and clear the codes. Most auto part stores can clear them.
The 1647 indicates a short to ground and that would blow the fuse. It could also mean your O2 sensor is shorted. You will need to clear the codes and see if they come back. I would also keep an eye on that fuse.

 

Fuse F42 is 5 amp connected to fuel inertia cut-off switch from what I've been able to find (Haynes manual wiring diagram), so I don't think it relates to P1647. My search for that turns up as Bank 2 oxygen sensor (upstream one). BTW, Bank 2 cylinders are 2-4-6, the ones nearest the radiator. Bank 1 cylinders are 1-3-5 near the firewall. You do have the 3.0L V6 engine right OP?

 

on the 2003 xtype I was told F42 is Bank 2 fuse

 

Got Owner's Manual? On page 158 of mine fuse F42 is 5 amp rating, serves the power steering module. The only ones I see referenced (p. 155) for the oxygen sensor heaters are F21 and F20, both 30 amp. In my book 30 amps is the highest-rated fuse I find. 30 amps on the O2 sensor heaters makes sense because they're a high current draw when you start a cold engine. Maybe a member here with more electrical knowledge can help with your issue. If it were my car I'd replace F42, clear codes and then see what comes back. How many miles on your car? From what I've seen, oxygen sensors are good for about 100k miles or less.

 

The OEM made a major wiring change in the 2004 models. The fuse locations and designations were changed for all 2004 cars after March 2004.
Fuse 42 prior to March 2004 is a 30 amp fuse for Oxygen sensor heater B. Fuse 38 prior to March 2004 is a 30 amp fuse for Oxygen sensor heater A.
Both fuses are in the engine compartment fuse box.

 

If fixed, the MIL will go off after 3 warm ups. The code will silently remain stored for a long time in case a tech needs to diagnose something but such codes won't affect e.g. inspections.

 

Can you tell me what a warm up consists of? Do I need to drive it for a certain amount of miles

 

Here are what the drive cycles consist of:

DIAGNOSTIC MONITORS DRIVE CYCLES
Technicians can ensure that an OBD Monitor drive cycle is completed and that all or specific components have been checked by completing a specified drive cycle.
Use the following service drive cycles to confirm that the components and subsystems covered by the Diagnostic Monitors are operating correctly.
HEATED OXYGEN SENSORS MONITOR DRIVE CYCLE
Upstream (Universal) oxygen sensors:
1 Engine OFF; cooling fans inoperative > 20 seconds.
2 Start engine and bring to normal operating temperature > 82 °C (180 °F).
3 Drive the vehicle between 3000 – 4000 rpm at a steady speed. Lift foot completely off accelerator and coast to a stop within 30 seconds. Do not touch accelerator
pedal for 4 seconds after coming to a stop.
4 Repeat step 3.
5 Idle engine for 11 minutes.
Downstream oxygen sensors:
1 Start engine and bring to normal operating temperature > 82 °C (180 °F).
2 Drive the vehicle steadily between 48 – 97 km/h (30 – 60 mph) for 10 minutes.
3 Drive the vehicle above 3000 rpm in 4th gear at a steady speed. Lift foot completely off accelerator and coast for 30 seconds.
Oxygen sensor heaters:
1 Start engine and bring to normal operating temperature > 82 °C (180 °F).
2 Idle engine for 3 minutes.

 

engine warm up is essentially what it sounds like but google if you want full info

 

on my 2004 x type 3.0 i have no power to my upstream sensor left bank
