P0131 1/1 02 Sens Shorted To Ground
P0132 1/1 O2S Shorted To Voltage
P0145 1/3 O2S Slow Response
Replace the spark plugs with Champion Copper plugs and gap them to .040 and install.
Next check fuel pressure at the rail. Anything under 50 psi I would replace.
Check the coil, do you have spark?
Also ensure there is no oil or corrosion in the drivers side O2 sensor before the CAT. Replace this sensor with a Desno or NTK sensor only and reset the PCM.
The P0145 might just clear when the system is running correctly.
