How much does it cost to replace fuel pump in Mazda 626?

Switch the key to “ON” and the fuel pump should be heard running for a second or two. Listen at the gas filler if necessary. If you do not hear the pump the inertia switch should be reset, it will “click” when it is reset. The average cost for a Mazda 626 Fuel Pump Replacement is between $726 -$782.

What does p0016 stand for in Mazda 6?

P0016 is know to occur in the Mazda 6 when the Crankshaft Position Sensor and the Camshaft Position Sensor are out of alignment by a certain number of degrees, or if there is a sensor issue. We’ll explore the symptoms and causes directly below. P0016 refers to which camshaft position sensor is out of time with the Crankshaft.

How to check Mazda p0016 crankshaft and camshaft correlation?

If the PCM detects that the Crank and Cam signals are out of time by a specific number of degrees, this P0016 Mazda code will set. First, visually inspect the cam and crank sensors and their harnesses for damage. If you notice broken/frayed wires, repair and recheck. If you have access to a scope, check the cam and crank patterns.
