Hi one of the door actuators is faulty. The rod is not reaching its full stroke to complete the locking cycle. It thinks the door is not fully closed and it releases the lock. Try the drivers one first it’s the most common and gets most use. Disconnect it first and then try.

Error code po174
DTC P0174 - System Too Lean (Bank 2) This DTC is very similar to P0171, and in fact your vehicle may show both codes at the same time.
A code P0174 may mean that one or more of the following has happened:
Possible solutions, a lot of times, cleaning the MAF sensor and finding/fixing vacuum leaks fix the problem. If you're on a tight budget, start there, but that may not be the fix for certain. So, possible solutions include:
- The MAF (Mass Air Flow) Sensor is dirty or faulty
Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
- There could be a vacuum leak downstream of the MAF sensor
- Possible cracked vacuum or PCV line/connection
- Faulty or stuck open PCV valve
- Failed or faulty oxygen sensor (bank 2, sensor 1)
- Sticking/plugged or failed fuel injector
- Low fuel pressure (possible plugged/dirty fuel filter!)
- Exhaust leak between engine and first oxygen sensor
On V6/V8/V10 engines, Bank 2 is generally the side of the engine that doesn't have cylinder #1.Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
- Clean the MAF sensor. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
- Inspect all vacuum and PCV hoses, replace/repair as required
- Inspect all hoses and connections in the air intake system
- Inspect and/or test the intake manifold gaskets for leakage
- Check for a dirty fuel filter and proper fuel pressure
- Ideally you'll want to monitor short and long term fuel trims using an advanced scan tool
- If you have access, you may want to run a smoke test
Thank you for using FixYa, have a nice day.
