CEL two codes

[CDover]

I'm new hoping for help. Getting p1129 ans p0152. I changed the bank 2 sensor 1 o2 from Orielys Auto Parts. Could Mopar brand be the key here or do I have a short potentially in the connector wiring harness?

Always use OEM Sensors for whatever brand you are attempting to repair . They may cost a bit more , but not repeating the work is more cost effective.

"P0152" doesn't show as a legit DTC in my info system... As for the P1129, Throwing an Oxy or A/F sensor at it is careless, thus expensive. my info lists 13 possibilities as to why the code is set. THIS is why a DIAGNOSIS is mandatory, unless you are wealthy!

What could cause P0152 code?

Code P0152 is triggered when the Engine Control Module (ECM) detects an abnormally high voltage (approximately 1.2V or higher) on the signal circuit of the bank 2 sensor 1 Oxygen (O2) Sensor for an extended period of time. Bank 1 is the bank with cylinder 1, bank 2 is the opposite bank.

P1128 Bank 1 Upstream, P1129 Bank 2 Upstream Closed Loop Fueling not Achieved

Diagnose and repair any other O2 sensor DTCs that are present before continuing with test procedure. This test works best if perfromed on a cold engine (cold soak). Turn the ignition on, with the scan tool, read the engine cooland temperature (ECT) sensor value

- O2 sensor signal circuit
- O2 sensor circuit
- O2 sensor
- ECT sensor operation
- Engine Mechanical Problem
- Fuel filter/pressure regulator
- Powertrain Control Module (PCM) <--- should be considered LAST

Has the fuel filter ever been replaced? Some diagnostics are in order.
