Codes: 1996 to 1998 Volvos

A Little Background on On Board Diagnostics

OBD-II grew out of an effort in the late 1960s by Volkswagen to computerize the monitoring of an automobile’s running status. The thinking went like this:

Is something wrong with the car? Well then let’s record it, remember it, and spit it out for the owner or technician.

That’s what your Volvo does. That’s where On Board Diagnostics came from.

The US state of California required all 1991 new cars to have a computer that would not only facilitate this recording of faults, but provide a common method of retrieving them across brands and models [citation]. It was an open format, in other words.

The “Middle” Year Volvos: 1996-1998

OBD-II diagnostic trouble codes are 4-digit, preceded by a letter:

  • P for engine and transmission
  • B for Body
  • C for Chassis
  • and U for Network

  1. Just had a 98 s70 come in with no A/C good pressure on the system (checked with A/C gauges) checked fuses all good, scan showed code 225 on the engine diagnostics section. cleared code A/C started working. so maybe just a glitch in the system.

  2. i overheated my 850 volvo 1996 model it started to make all sorts of noises frm the motor nd eventualy stoped i thought i had siezed the motor but the nxt day the engine turned over at a rapid pace leaving me to believe it was knackerd ive removed timing belt cover belt ok taken starter motor off seems ok no water in oil but it fails to restart

    I have a 1998 S90 volvo. I did a diagnostic test and it reads P0740. The check engine is on, flashing arrow comes on, there are three letters by the gear shift (WSE) The light flashes from W to E rapidly. What is the problem

  4. I have a 1998 S90 volvo. I did a diagnostic test and it reads P0740. The check engine is on, flashing arrow comes on, there are three letters by the gear shift (WSE) The light flashes from W to E rapidly. What is the problem

  5. I have a 98 s70 glt. The code reads p0120. Is this why it doesn’t want to go when I give it gas? Also how do I fix this?

  6. Have 1998 xc-70. has intermitent stalling and slow restart. Check engine light on. Generic codes have been PO-171 bank one system too lean and PO-103- mass or vacuum air flow circuit high input. Does this sound like air flow mass meter after air filter. Also 4-pin connector plug has I assume dielectric grease. Would this grease effect readings and is air flow meter gone and what should resistance readings be.
