Question about 2000 Volvo S40
I have a Volvo S40 (year 2000, mileage: 156800 now), and I saw a check engine light (P0014 - Exhaust Camshaft Position - Timing Over-Advanced (Bank 1)) on April 01. I deleted the code with my code reader on April 04. The code came back on June 2 (After 2 month ). The timing belt was changed at 105K. The car is in a good condition (like a new car), Can you help me please to fix the problem ?
Camshaft position sensor could be problem.

This is a common issue particularly with vehicles that have had some neglect to the oil change routine. The VVT solenoid on the top of the valve cover gets clogged with thickened or sludged oil.
Replace the VVT solenoid and gasket with a new unit and clear the codes.

take out number one sparkplug, take the cam cover off. turn the engine of with a spanner on the bottom pulley. make sure number one piston is at TDC, now check to see if the inlet&outlet valves are close. and the piston is all the way at the top, do this with a long screwdriver to make sure it is.
if everything ok, then it will be a ignition problem.

The best thing is to go to your local Volvo maintenance shop or Volvo experts to find out whats the problem..usually the coomon ones I think is the programs inside its ECU unit..you try this..ask the volvo experts to reset the ECU and lets see..if problem arise then it is no doubt you might need the sensor..hope this help..

Hi, Since you have both codes Fuel system lean and MAF low I would bet money on that you have an intake air leak after the throttle. Check all hoses connected to the intake manifold, gaskets, injectors are put in place etc.

I think your sensors are pattern parts and the readings /resistances are not the same as the original parts ,try some bosch units is my first suggestion ,
