Hi i have had a problem lately and just cant figure out whats wrong so i thought maybe you guys could help. I have a 96 volvo 850 turbo. For a while ive been having on and off problems with the blinking arrow light when i got the code read it said pnp so for a while i did the ranking trick to get it to work. Eventually the pnp went so i bought and replaced it. The blinking arrow went off but the cel didnt so i drove it aeound hoping it would shut off. It never did. So i left it as i started a new job. When i went back to it the arrow is blinking again with cel but there are still no codes and the car drives fine. Im not sure what the problem could be i planned on changing the tranny fluid just a quick one not a full flush hoping tht would help but i thought id ask for some opinions first. Thanks
