Sputtering

My friend has a 06 Rubi that is hesitating on acceleration. Throwing p0131, p0132, p0151, and p0152. All O2 sensor codes. No valve in the fuel rail to test pressure. No other codes are in memory. Any ideas? I was thinking fuel issue but would hate to spend that much just throwing it at it. It has 71K miles. Thanks in advance.

Anyone have any ideas?

Chances are the o2 codes are a response to the poor running condition. Check for major vacuum leaks, check that pcm connections are tight, and do check the o2 wiring and pcm wiring to ensure there is no rubbing or rodent damage.

All wiring and connections are good. No vacuum leaks.

Try taking the wiring harness loose at the bulkhead on the firewall and cleaning it with a dielectric cleaner.

Check fuel pressure.

No place to check pressure. There is no valve on the rail

Mopar tool 6539A I believe is what you are looking for, about 50$ from what I can remember. It creates a pressure loop and has a built in gauge.

Could one bad O2 sensor make the other throw a code?

Not that I'm aware of but with electronics the way they are now.... Anything is possible.
