check engine advice
Hi all,
Recently my check engine light began to blaze on my dash brighter than 10,000 suns. I checked the codes and got 10 pcm p0410. I am pretty for sure this relates to the damned air pump. Am i right on this or not and can you give me advice as to how to deal with the problem.
Also...I recently went to a chevy dealership (Burns chevy in Rock Hill, SC) to get the oil changed. They put 10w30 mobile one in the engine. Why wouldn't they, it only says Mobile 5w30 ON THE FRICKEN OIL CAP. Should I go back demanding 5w30 or is 10w30 OK for the engine?
Thanks for the advice all,
Jason Powell

Oil Choice!
10w30 isn't a bad thing. Alot of use run a thicker oil in the Summer due to heat, better protection. In the Winter, 5w30 is what you want. The oil won't thin out due to heat that bad, 'cause of the cold.
10 pcm p0410 is a reference to your Secondary Air Injection. If the changed your oil, they probably messed with your air filter. Check from the intake housing moving towards the front. Something may be pinched or not connected.

I think P0410 is Cat Inefficient. The shop manual states check for leaks and if none found, replace the Cat Converters. 10W30 will not hurt anything IMHO. Welcome to the Forum.

An AIR pump is used on this vehicle to lower tail pipe emissions on start-up. The PCM supplies a ground to the AIR pump relay, which energizes the AIR pump. The PCM monitors the HO2S voltages to diagnose the AIR system.
During the AIR test, the PCM activates the AIR pump during closed loop operation. When the AIR is activated, the PCM monitors the HO2S voltages and short term fuel trim values for both banks of the engine. If the AIR system is operating properly, the HO2S voltages should go low and the short term fuel trim should go high.
If the PCM determines that the HO2S voltages for both banks did not respond as expected during the tests, DTC P0410 sets. If only one sensor responded, the PCM sets either a DTC P1415 or P1416 to indicate on which bank the AIR system is inoperative.
