SOURCE: Where is the fuel filter in a Volvo S40 2005

Yes that is correct. The only filter is inside the fuel tank, and as I recall its a non exchangeable filter. It just gets replaced with the fuel pump when it goes bad

Volvo Radiator, Thermostat and Sensors Your cooling system's temperature controls include all coolant temperature sensors, Volvo thermostat, Volvo radiator or expansion tank cap, cooling fan(s) and fan clutch (if equipped). These cooling system parts function primarily independent of the engine but control the engine either through cooling or by sending control signals to your Volvo's electronic systems.
The Volvo thermostat is a spring-loaded valve that opens and closes based on the temperature of the coolant flowing through it. A high temperature reading followed by a drop to normal temperature (or a continuously low temperature) is a common first sign of a sticking Volvo thermostat. However, many other conditions may cause these symptoms, so you need to know how to eliminate each possibility.
The Volvo radiator or expansion tank cap is also a spring-loaded valve reacting to system pressure. It serves to maintain proper system coolant level at predetermined pressures. It must always be replaced with an exact replacement cap with the same pressure setting. Never use other caps except for short-term emergencies!
A belt-driven fan blade for pulling air through the Volvo radiator is usually on the Volvo water pump pulley and should have a fan clutch to control it. The fan clutch allows the fan to turn with the belt at low engine speed and "free-wheel" at higher speeds. A bad fan clutch either doesn't allow the fan to spin at low speed (overheating in traffic) or doesn't allow it to free-wheel at high speed (potential overheating on highway or reduced gas mileage).
An electric fan can be either by itself (usually front-wheel drive) or auxiliary (used with a mechanical fan). Both types are controlled via a temperature sensor - in the Volvo radiator or upper Volvo radiator hose or on the Volvo thermostat or Volvo water pump housing. This sensor is usually an on/off type switch with a fixed temperature setting. (Some vehicles may have 2-3 settings for multi-speed fans.) This sensor is commonly called an "auxilliary fan switch".
Other common temperature sensors are: 1) gauge sender (variable output); 2) warning light sender (on/off type); 3) lambda and/or fuel injection sensor(s) (variable to control fuel injection settings); 4) thermo-time switch (cold start valve control). Your Volvo may have other sensors as well.
Temperature control is critical to both performance and emission control. Unfortunately, this system is the most difficult to troubleshoot without proper equipment and diagrams. It's even more difficult with computers that adjust timing, idle speed, vacuum and fuel delivery automatically to make up for potentially faulty temperature sensor signals.
Maintenance of your cooling system sensors is virtually impossible since there's nothing really to "maintain". Keeping them clean both internally (coolant replacement) and externally (engine cleaning) is the best way to ensure trouble-free driving. Checking and replacing all parts at the factory-recommended time or mileage limits helps as well

SOURCE: The OBDII scan read code P0236 y P0171 yesterday

P0236 Turbocharger Boost Sensor A Circuit Range/Performance

  • P0171 System too Lean (Bank 1)
  • P0237 Turbocharger Boost Sensor A Circuit Low
  • P0101 Mass or Volume Air Flow Circuit Range/Performance Problem
  • i would start, given these codes, to look around the air duct assembly for signs of cracks or disconnected hoses resulting in a vacuum leak.

    2006 volvo s40 2.4I. Where is the ECT(engine


    Instructions
      • 1 Open the engine hood by pulling the hood release latch located on the lower kick panel on the driver's side of the Volvo S40. Lift the hood up and prop it on the hood prop.
      • 2 Locate the steering shaft that extends from the firewall to lower suspension located inside the engine compartment, by the front right wheel. Halfway down the shaft, you will locate the power steering pump. The pump is a black container that bolts to the driver's side of the engine block. On the top, you will find a cap that says "Power Steering Fluid."
      • 3 Look to the left of the cap. Bolted to the power steering pump is the thermostat temperature sensor. The sensor has a black round cap and a black wire extending out of the top.

    I have a 2006 Volvo S40 and the check engine light has recently come on. I just had the 60k mi service about a month ago.


    Have the vehicle scanned at a local parts store and have them retrieve the code. Once you have the code, let me know and we can diagnose it properly and effectively.

    I have a 2004.5 S40 2.4i. It is currently


    From your codes it sounds like your problem is in the fuel system.
    P0171 is air-fuel ratio is lean, malfunction.
    P0192 and P0194 is low pressure detected in fuel rail.
    So you need to look for leak/s, fuel pressure, fuel regulator, and fuel filter. good luck.

    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.
