2007 Volvo S40 2.4i Sedan - Answered Questions & Fixed issues

my volvo car dose want to start when i want to switch on the say( ANTI-SKID TEMPORARILY OFF) and all light right hand said coming red and left hand said coming yello.

Is there actually fuel in fuel lines?

Take it to a good Transmission shop, sorry but it won't be cheap.

look for a loose or broken vacuum hose connection , pcv valve fault

I had the same issue, reason Of the vacuum pump to work continuously is either a leak in the vacuum pipes btween the pump and master cylinder or "which was my case", the vacuum switch or sensor between the master cylinder and vacuum pipe is not functioning properly. Replaced and everything works fine.

Your ignition needs replaced. They weren't the best on Volvos; especially if there is a lot of weight on your keychain.

A good way to check for ground continuity is to use a multimeter. If the socket has two wires , one will be positive + 12 volts DC or so. The other wire and connector in the socket will be the ground. Put the multimeter on DC volts, 20 volt range, and place the probes into the socket. If you know which socket wire is positive, place the positive(red) probe in that socket connector, and the black probe into the other connector, which is the ground. When you turn the headlights on, you should get a 12 Volt reading, more or less on the meter. If the meter shows a negative sign or the needle deflects to the left on an analog meter, reverse the probes in the socket. If there is no voltage reading, giggle the wires in the socket to see if the problem is in the socket. Also, keep the positive probe in the socket and make good contact with the black probe on a part of the car body. If the meter shows 12 volts then it shows that the socket is getting current (Voltage), so you know the positive wire is good. You can also check for continuity of the ground wire. Turn off the headlights. Put the meter on the continuity setting. On this setting, when you touch the two probes together you will here a buzzing sound. Place one probe in the ground connector of the socket, and make contact with the other probe on a good ground on the vehicle. It doesn't matter which probe is connected to ground. I there is a good ground, the meter will buzz. If it does not buzz, there is a bad ground betwwen the socket and the vehcile ground.

Yes you have a bad headlight socket gound.

alternator belt braking would not stall the engine but your dash would of lit up like a christmas tree. you will need to have the engine on an obd reader to see what the problem is. did the belt snap or was it stripped ? alternator over load would cut the engine out check the fuse in the engine fuse box there is 2, 80 amp fuse in there check these are fine.

I am thinking faulty injectors and/or excessive fuel pressure in the fuel manifold . Run fault codes again ensuring that the cables used and the procedure to connect is adhered to as there will be a fault code recorded but not being read

Load test the battery if possible, but more than likely the battery has become unable to hold a good enough charge to start the vehicle. I would also clean the pos. and neg. terminals of all corrosion and make sure they are tight.

try a different key, also can try unlocking driver door with key to disable the immobilizer

Probably, you will need a bearing puller in most cases.

Hi there:Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. Another term for excess fuel is "running rich." Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm. Excess fuel will usually effect engine performance, reduce fuel economy, and produce a fuel odor.How did the fuel get into the cylinder in the first place? Some of the causes of excess fuel are a carburetor that is out of adjustment, a faulty fuel pump, a leaky fuel injector, or a faulty engine computer or computer sensor. If black smoke is present, check the engine oil as in the white smoke example to make sure excess fuel has not contaminated it. Do not start the engine if a heavy, raw fuel smell can be detected in the engine oil. Call your mechanic and advise him of what you have found.Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.Thank you for using FixYa.

Most lean O2 Sensor Codes are from vacuum leaks,
you should be able to find and fix yourself

For $50.00 & 15 minutes of your time,you better not
be paying someone to do an O2 Sensor

1. Remove the driver's side soundproofing panel

2. Remove accelerator pedal

3. Fold carpet back. Remove 3 retaining screws, and fold up cover

4. Remove filter by pulling it out behind the brake pedal

NOTE: The direction of air flow is indicated on the top of the filter.

5. To install the filter, ensure that the filter is installed with the text side acing up and so that the arrows on the filter point straight back into the vehicle

6. Install air filter by compressing it slightly and inserting it behind the brake pedal.

7. Clamp the cover in place at the rear edge. S

8. crew the cover into place at the front edge using the 3 screws.

9. Fold back the carpet.

10. Install the accelerator pedal

11. Install the soundproofing panel

PLACE PLASTIC BAG OVER ALTERNATOR TO KEEP FROM GETTING POWER STEERING FLUID IN IT.WILL DAMAGE IT.USE A SIPHON REMOVE ALL POWER STEERING FLUID IN PUMP RESERVOIR.THEN REMOVE REMOVE BOTH POWER STEERING HOSES CATCH WHAT FLUID LEFT IN THE POWER STEERING PUMP IN A DRAIN PAN UNDERNEATH THE VECHICLE TRY NOT TO GET POWER STEERING FLUID ON CAR PAINT IT WILL REMOVE CAR PAINT.AND POWER STEERING FLUID IS DANGEROUS.ITS A NEW KIND TRY NOT TO GET ANY ON SKIN OR CLOTHES WEAR LATEX GLOVES WHEN HANDLING IT.

Signal too high

Checking the wiring
Check the cable between engine control module (ECM) terminal #B23 (#C23) and leak diagnostic unit terminal #2. Check for a short-circuit to supply voltage.
Remedy as necessary.
<the terminals are marked>

This usually means the computer is having issues!

This is really difficult... A friend of mine tried to fix this and it took over an hour. Anyway this is how he did it.. First take off the panel from behind the radio. (3x T25 screws) Then remove the big panel under the steering wheel.

Then you'll need to remove the accelerator/gas pedal. To do this remove the 3 x 10mm bolts underneath and the 2 on top. When there unbolted remove the gas pedal.
Drag the carpet back that's directly under the steering wheel to show the black cover panel with 4x 7mm screws that underneath. Take those screws out and the cabin air filter will be underneath. Replace filter and put everything back together EXACTLY how you dismembered it =)
