Does anyone know why a 02 ram would shut off and throw 02 sensor codes?

Asked by GuruJ4J52 Jul 21, 2020 at 10:08 PM about the 2002 Dodge RAM 1500 SLT Quad Cab RWD

Question type: Maintenance & Repair

My truck started sending codes to change
the 02 sensors so I did after that it wouldn't
start at all I ended up changing the ECU and
then it started to send the code for the
downstream 02 sensor being bad again so I
changed it again and now it's showing both
02 sensors are out again and will
intermittently have the check gauges light
come on the dash and then just shut off .I
have no idea what to do at this point if
anyone has any advice I would really
appreciate it

No I honestly haven't but mostly because it's such a quiet truck and I always thought that when the catalytic converter went out it became very noisy but will check it out tomorrow morning

that's where i would start if its plugged and not flowing freely it can throw 02 Sensor codes

Awesome thanks so much At this point I'm desperate to figure this out will look into it tomorrow morning asap! Really appreciate your help
