Inlet air temp for the engine is located inside the MAF
the "air temp", like the one for the outside temp that is displayed on the dash is located in front of the condenser

2001 Volvo s40 seems to stall and not start for ten to 15 min. Also has high temperature reading that is false as car is not really hot.


You need to look at the temp sending unit it's probably faulty anthor issue with volvo is dirty throttle body's this raises havoc on the car they idle up down all over the map also you should change the thermostat too as a precautionary measure make sure it's the right temp for your year of your car thanx Chris

The OBDII scan read code P0236 y P0171 yesterday today read P0237 y P0101 whats the problem?? Is a Volvo S40 2002 1.9T


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.

    Need insructions on how to replace 02 sensors on a 2004 Volvo S40.


    1st lets look at the explanatioon of this code, it is not always the sensor at fault, the sensor can just be a symptom of another problem.

    Causes A code P0133 may mean that one or more of the following has happened:
    • The oxygen sensor is faulty
    • The wiring to the sensor is broken / frayed
    • There is an exhaust leak
    Possible Solutions The simplest thing to do is to reset the code and see if it comes back.
    If the code comes back, the problem is more than likely the front Bank 1 oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions:
    • Check and fix any exhaust leaks
    • Check for wiring problems (shorted, frayed wires)
    • Check the frequency and amplitude of the oxygen sensor (advanced)
    • Check for a deteriorating / contaminated oxygen sensor, replace if necessary
    • Check for inlet air leaks
    • Check the MAF sensor for proper operation

    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.
