I got this after filling up with fuel the other day, not sure if worth mentioning it was costco fuel, car seems to be running fine. however could it be my exhaust as it has been blowing for some time but not got round to fixing it yet as don't use much.
When I shake exhaust you can hear it is full of crap, maybe partially blocked. Will be fixing as soon as however likely not until NY. It's an 02 2.6 and no work has been done on anything recently so light has just come on.

I've heard this could be caused by maf sensor, do i need to get a code reader and check what's happening?
-
That code relates to a lambda sensor...
P0150 O2 Sensor Circuit High Voltage (Bank 2 Sensor 1)
P0150 O2 Sensor Circuit Slow Response (Bank 2 Sensor 1)
P0150 O2 Sensor Circuit No Activity Detected (Bank 2 Sensor 1)
P0150 O2 sensor circuit malfunction (Bank 2 Sensor 1)
Wouldnt have thought that would limit you though...
What protection did you put in place before soaking all the engine? (never a good idea)

How do I tell which one it is out of the 4, or is it all 4?
-
if the exhaust is so bad remove the o2 sensor on bank 2 and check its not blocked. but if the exhaust is as bad as you say it is then its no good it will have rust build up in the boxes limiting exhaust gases and building up in the exhaust this will make the sensor unable to adjust fuel etc. and be out of range of the sensor to adjust, and if the back box is the type with the webbing in side the rust build up will be stuck around the pipe. but you really need a new exhaust fitting. its not good on the engine with a damaged exhaust it can do damage to the cats.

What i've been thinking myself, backbox is full of crap, and centre sections holed. Am goin to replace as soon as i can.

Also noticed my temp reading is showing that famous f__oC display. Either the water leak got into, or at least dampened, circuits, or something related to code perhaps? There was a wedge shaped slab of ice on passenger floor after heavy rain then froze. Car seems to be going downhill without me really doing anything lol. Lets hope i can get this all sorted in NY as im in total cant be bothered with anything right now mood!

Been out in the snow/ice?
A quid bets ten that the sensor is either missing or knackered...
New ones are less than a fiver and fitting takes less time than typing this post ;)

Not really been out in snow or ice but roads were loaded with grit and I had been washing the underneath to clean the grit off. Strange how temp reading not working now either, coincidence?
-
temp sensors can just go, but it can also be damp in the sensor plug. cold temps shrink the rubber seals same on anything else over time and the age of the seals.

Bank 2 sensor 1 is left bank nearest the cylinder head
