As i was driving back from work today, my check engine light came on. The car continued to run well and i just had done an oil change the day before. I looked up the codes and it came up with P0161 and P3699. ran some tests and this is what came up. i attached the full report if anyone was interested.

MID:$7e TID:$33 - Max: 817.70001g Min: 5,543.2002g Test result value: 6,552.30029g FAIL ---- MID:$81 TID:$3b - Fuel System Monitor Bank 1 Max: -2,457.6001 Min: 2,667.19995 Test result value: 1,561.59998 FAIL ---- MID:$81 TID:$40 - Fuel System Monitor Bank 1 Max: -2,457.6001 Min: 1,028.80005 Test result value: 1,561.59998 FAIL

from my understanding it might be a fuel pump issue from what my mechanic told me, but i think it might be a fuel filter problem.

Has anyone had this issue before?

Your mechanic is right it is the Auxiliary Fuel pump. I had the same 3699 code before, and my mechanic replaced the pump and fuel pressure sensor on the rail due to fluctuating fuel pressure.

the BS is going in next week for a full diagnostic but much appreciated!

I would agree with shellx

3699 - Doesn't this mean that the

upper limit value is reached

Please update how diagnostic went


Thank-You
