2007 O2 Sensor Ohm?

Anyone know the resistance of the 2007 O2 sensors? My maint manual only tells you how to remove and replace.

Trying to trouble shoot a rough idle would like to check the resistance of the O2 sensors.

Thanks !!

Is it throwing a code?

P0131 Front O2 sensor low (lean)
P0151 Rear O2 sensor low (lean)
P0132 Front O2 sensor high (rich)
P0152 Rear O2 sensor high (rich)
P0134 Front O2 sensor open/not responding
P0154 Rear O2 sensor open/not responding

No codes , just running rough in traffic and idle when warm. Cold Idle seems to be ok

Check for any intake leaks?

KN airfiler ? Could the high flow airfilter be an issue? No other upgrades. Only other non stock item is wrapped exhaust pipes.

 

[glider]

Wrapped exhaust pipes not a good idea, the metal gets very brittle.

The K&N shouldn't be a problem but it will cause a lean condition that may be the issue, more like manifold to head leakage.

Will check for leaks. Maybe throw the stock air filter on and see if it make a differance. Thanks for the heads up. Will let you know what I find.

This is what you need, it's in the Electrical Diagnostic Manual
