CEL codes related to oxygen sensor & P1539
 
Hi Guys,

My car: 1998 Porsche Boxster

So I had the following codes come up along with a check engine light on the dashboard.
P0154 Oxygen Sensor Ahead of Catalytic Converter (Cylinders 4 - 6) - Interruption of Signal (inactive bank 2 sensor 1)
P1115 Oxygen Sensor Heating 1 After Catalytic Converter - Above Upper Limit
P1119 Oxygen Sensor Heating 2 Ahead of Catalytic Converter - Below Lower Limit
P1539 Camshaft Adjustment, Bank 2
The smog check shows its running rich at 1.48 CO% which is 0.48 above the max allowed at 2500 rpm.

Ok so dumb question but definately need some clarification on first is:
Where is bank one and bank 2 located (passenger or driver side on a left hand drive USA 1998 Porsche boxster) and which cylinders are they connected to?

When checking out the engine after following the forums thread and getting to it by half opening up the top, I noticed rat poop and the front trunk of the car had the makings of a rats nest --- am wondering whether the rats must have chewed on some wiring and this is what is causing the problem.

How does one go about checking the wiring connections? does anyone have a schematic diagram to share on oxygen sensors wiring?


Thank you kindly
Natasha.

About 80% of the rodent damage we find on the 996 and Bosters is chewing of the wires at the oxygen sensor. They seem to love the engine harness wiring. your best bet is to take it to a reputable shop and then call your car insurance company, your bill may very well be a couple of thousand when you have taken care of all the damage. It is covered under your comprehensive coverage.

The PVC insulating material can have peanut oil content. Same applies to home installed wiring. Many house fires can be attributed to mice infestation and shorted AC wiring.
