Hi All,
I need help here. I've got a '94 855 Turbo w/ 215k miles.
I've had a chronic check engine light w/ codes 433 or 143.
Front or rear knock sensor codes. I've replaced them both
twice now, including Volvo's SB on the '94 KS. I've totally rewired
them and the code or codes keep coming back. I've come to the
conclusion that I have an ECU problem. Anybody have similar problems?
Will other ECU's fit, namely from a '95 or '95R? Will a later ECU
fix this?
Thanks alot
Rod Brehm
