Ask Your Own Volvo Question

When your check engine light comes on the computer system detects a problem and will set and store a fault code and or codes. In order to determine what is failing we are going to need to know what the fault code and or codes are that are setting. Most auto parts stores such as Auto Zone will do a scan for you at no charge. If you can get the scan done and post back with them I will direct you from there as to the proper repair.

Have done that and they stated a tune up which I have done....this has been going on for 2 months

Okay can you tell me the actual fault code and or codes are that should be setting when the check engine light comes on?

I will have to check this out. This has been on going for 2 to 3 months I feel I have rebuilt the car.

If you can get me the actual fault code and or codes I can help you determine what has been missed here.

Ron,
Engine light went off when I put gas in my car (premium) stayed off for 3 days until I started using my A/C. Went to Auto
Zone, today and the error code read PO101 some sort of sensor that measures the volume and density entering the engine.

The common cause for the code P0101 to set on your S40 is usually caused by a failing Manifold Absolute Pressure (MAP) Sensor and in most cases if there are no intake air system leaks and or vacuum leaks then replacing the MAP will usually solve this code.
