I have a 1999 S40 T4 auto that doesnot spark, the mech says it is the cam sensor. Can this be true. Can I buy a used ECU and have it coded for my car. Help please.

I found three solutions somewhere, hope one works for you!
Good luck! Just tell me which worked.

. It went like this, turn radio on, when “code” is displayed push and hold “6” while pushing “power & volume” knobs at the same time. Let radio turn off while continuing to hold “6”. Turn radio back on by pushing both “power & volume” knobs at the same time. It worked on 98 V90.

#2 (JAPAN IMPORT)
-I emailed 2 Volvo Dealers and both replied 6666 is the code for all used Volvo imports from Japan, so I switched the ignition key to pos I for over 2.5 hours and "CODE" appeared, then pushed button 6 four times and the Radio swiched On. Problem solved.

#3
-we altered the client access code input protocol by “rebooting” the stereo (turning it off and on using the combined volume/power input) and, at the same time, holding down the “stereo preset 6” button. The stereo then transitioned into the authenticated mode, allowing clients to listen to NPR without proving identity.

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..

The car uses a lot of fuel, when the garage replaced the sensor the car used a lot less fuel but the sensor failed within a day and the engine management light came back on again. It's after the cat sensor, the one at the back. i don't know what type of sensor it is but it has a 4 pin white plug and is about 1meter long (part no is 308643308 ntk a4f ) if it helps. I just want to know if it is possible that the exhaust can damage the sensor if it is loose? The garage keeps replacing the part but it does not look like they are trying to fix the problem!! i will fix the exhaust first and try a new sensor again.
Thanks vagman54
