Check Engine Light went on my 2002 Volvo XC70. There were two codes: P0234 and P0236. I erased them. Immediately after I turned engine on, another two codes, P0236 and P0237, appeared.
Reason? MAP sensor was gone. Part costs me about 100 bucks at dealer.
It only took me 3 minutes to put the new one on. The easiest job I have done so far..... Look at the MAP sensor location. Could it be any easier?
