CODE 1420 PLEASE HELP... - Benzworld.org

Have a 97 E320. Have a PO1420 code causing my check engine light to illuminate. The code is Catalyst Temperature Sensor Failure
My question is where is this sensor located?? Is it where I can get to it and change it out, or get a dealer screwing and have it done there.

Thanks

P1420 is secondary air injection (air) valve solenoid-defective, fix is faulty wiring-fuse-air valve/solenoid-ECM
check the fuses first
