Question

2005 Ford Escape showing codes 122; 192; 452; 454, and 2196. This does not happen consistently; sometimes it will drive perfectly fine.

Answer 1

P0122 Throttle position (TP 1) sensor circuit low input

P0192 Fuel rail pressure sensor circuit low input

P0452 Fuel tank pressure sensor circuit low input

P0454 Fuel tank pressure sensor circuit noisy

P2196 Lack of H02S switch Bank 1 Sensor 1 Indicates - Rich

What all these sensor share and have in common and ties them as 1 circuit , is the signal return, You have a short. This includes the oxygen sensor . Somehow one of these sensor is causing the signal return to go low , Because this condition is remotely intermittent,  You may just want to have the FTP sensor closely inspected.

Here in this wire diagram what not show is the 02 sensor, and the FTP sensor, They all share the same connection and that is the signal return, clear the code, usually the first sensor that set a code may just be the one at fault.
