Question

The vehicle engine light is on. The code detected is P0174

Answer 1

Depends what the problem is. You may have a intake leak and the repair depends what part is leaking could be as simple as a small hose for a few dollars or a big gasket for several hundred. If the problem is an O2 sensor, the is a couple hundred dollars.

The more likely cause for your problem is an intake plenum gasket, which can cost you $200-$300 to repair.
