[jtquad]

Does anyone know what part i need to replace to clear these codes? I Have an ODBII Scanner and this is what keeps kicking up. It is on a 1996 Saturn SL2. Thanks ahead of time - Joe

P0133 Heated O2 Sensor Circuit Slow Response (Bank 1, Sensor 1)

the front O2 sensor needs replaced, most likey it is covered in carbon build-up

for the P1406, i'm not sure, i can't find the exact code, but take care of P0133 first and see if it comes back.

DTC P1406 EGR Valve Pintle Position Circuit

i don't know exactly what this code means, most EGR problems can be solved with a good cleaning.

take the EGR off, clean it with sensor safe carb and choke cleaner, spray a little into the passages in the head to, replace the gasket also.
