I have been getting an occaisional CEL so I took it to the mech to have it checked came back with 3 stored codes
p0420
p1456
p0134

Which he tells me are the sensors, Is this all I should expect or am I looking at a total cat replacement? And does anyone know of about what to expect cost wise on new cat/ sensors

According to my new SM, here's what they mean -

p0420 = Catalyst System Efficiency below Threshold
p1456 = Evaporative Emission Control System Leakage
p0134 = A/F Ratio Sensor Signal stuck lean

I bought an A/F Sensor a few weeks ago online, cost about $220. Easy to replace myself...

According to the manual, p1456 can be caused by a loose gas cap, among other things.

Hi KNOwtalent,

Did the mechanic reset the check engine lights?

If so, did they come back on after driving it?

Give me a call, I have a Scanner, we can check it out.
