2014年6月27日 · P013C-O2 SENSOR 2/2 SLOW RESPONSE - RICH TO LEAN 07 GC 3.7L. I've replaced the plugs (which badly needed it), all 4 O2 sensors, the bank 2 cat, and two bank 2 coils. (swapped the 3rd) I took it back to the muffler shop and he sealed up 2 pinhole leaks in the new cat. This fault has been going on for 3 years now.

The code P013C indicates the Bank 2 Sensor 2 HO2S sensor is reading a Slow Response and if this is the one that you replaced then the first thing you need to do is to make sure the replacement meets all Original Equipment Manufacturer (OEM) specifications.

2012年2月7日 · p013c-o2 sensor 2/2 slow response - rich to lean Theory of Operation The downstream O2 Sensor is located in the exhaust path behind the catalytic converter, is monitored for proper response to assure optimum catalytic converter efficiency.

Customer: I have the dreaded P013C fault code on my 2008 Commander. People have replaced a bazillion O2 sensors with no luck. The only real fix that I can find any info on seems to be a cat replacement. Everyone also has an opinion on when to replace O2 sensors as …

Now since you switched the sensor and did not move then we go to the circuit and or exhaust leak?

2015年7月21日 · Finally replaced PCV valve, and that solved problem. My theory is that valve was not sealing properly when throttle closed causing lean condition by introducing air not accounted for by the computer messing up P013c test. So, to answer your question, the exhaust needs to be airtight to the muffler.

Customer: 2015 Silverado 3500 6.0 gas. P013E P014A, P0158, P0138, P013A, P013C, P2271, P2273 present. Have already replaced both fuel pumps and sending units, cleaned out both fuel tanks and fill with good clean 93 octane, replaced all plugs and wires, replaced all 4 O2 sensors, replaced both Catalytic converters and replaced all 8 fuel injectors with injectors from Chevy.

Has P013E, P014A, P0158, P0138, P013A, P013C, P2271, P2273. All O2 sensors are new, has new plugs and wires, no misfires present. Fuel pressure is at 60 PSI idling but slightly bouncy between 55 and 60 PSI. Does not drop under load or acceleration. Took fuel sample and has no water mixed but to see some sand and "grittyness" present.
