my 2003 focus lx 2.0L L4 SOHC ~18,000 miles has had the engine light so I went to autozone to read the code.
Autozone obd2 printout says "P2195 lack of heated oxygen sensor- Bank 1 Sensor 1 HO2S11 switch- sensor indicates lean"
they said "Your car is burning more fuel. It's a common problem. It's usually the 1st sensor to go out. It's possibe to DIY. It looks like a spark plug in the exhaust pipe b4 the catalytic converter by exhaust manifold."
I checked with Herko Automotive Group and they said "For your car 2003 FORD FOCUS 2.0L L4 SOHC in the position sensor 1 (Upstream) you need the oxygen sensor number SG1813."
1. I think I see whee the bank 1 sensor 1 in front of the engine but can someone post a pic highlighting the location
2. How reliable is this advice from autozone & herko? Should I just replace the sensor or what's the next likeliest fix for this?
have the same problem?
