Hello,
I am receiving the following three error codes from my scanner can someone help me determine which is the bad culprit?

P0327, P1238, P0134

I have a wife who brain farted while driving home from work. She drove her 99 v70 with 228k miles through a dip in the road that had about 2.5 feet of rushing water. She made it out of the dip but the car suddenly stopped running. I got the vehicle towed home and dried the maf sensor out and checked the tube to the manifold for water ensured it was dry removed the wet air filter, oil was not chocolate like, the tranny fluid looked good and then left the vehicle to dry out in the garage tonight I blew dry everything under the hood with a compressor to ensure drying. After two days the vehicle would still not start. It cranks and sounds like it is just about to start but just will not catch. So tonight I connected my scanner and received these three codes in order of appearance on the scanner p0327, P1238,P0134 I think she blew a sensor while trying to make the car a submarine but I just don't know which one? If anyone has any idea any help would be appreciated I am wondering if it is the maf sensor?

p0327 is knock sensor, P1238 is air metering problem and P0134 is front o2 sensor. The only code that causes me concern is the P1238 MAF sensor may have shorted out. Remove the MAF and clean w/MAF cleaner. If no result, I would focus on that unit for further diagnosis.How are you with a Digital Volt Meter?

 

I will get one and just tell what to do. I haven't used one since oh I don't know when. When I was drying everything out the fragile little wires in the sensor were intact and I (dumb)***umed it was alright. is there a way to test it without swapping it out with another?

 

ok so I was tinkering with it again tonight and decided to clear the codes to see if or which one is the hard fault. They all cleared but still will not start. it is now not giving any error codes at all. I think the codes that were being thrown out were the ones that happened when she was in the water. The question now is what is preventing it from starting. One of the independent volvo specialists suggested to check out the
ETB He was saying this is problematic for this year vehicle? Any thoughts anyoone?

 

did water get into the cylinders? remove the plugs and check them out. if the air filter was soaked then there is a chance.

 

no water did not get into the cylinders. But Today in the daylight I did notice water had gotten into the ecu unit container. I am hitting it with a compressed air and a blow dryer from a distance to ensure drying next then we will see.

 

sounds like a real mess.

 

Have you checked the fuse / relay box under hood for water?
