Engine Performance problem
2002 Mazda MPV 6 cyl Front Wheel Drive Automatic 72000 miles

2002 Mazda MPV ES 6-cyl non-California car w/72000 miles.

Have Check Engine Light, error code readout is P0051, "HO2S heater (Front, LH) circuit low". I believe this is the O2 sensor nearest the radiator, before the catalytic conv. Am I correct? Will Bosch 15314 be the correct OE replacement part? How do I gain access to the O2 sensor, i.E, what do I have to remove to be able to get at it, clearance space appears to be non-existant?

Can you help?

Do you
have the same problem?
