Newmar workhorse engine light

[Bill Healy]

Periodically when it rains I get an engine error light "P102" "low air flow". After sitting overnight and drying, the light the light does not come back on. Does anyone have a similar problem and how did you resolve it?

Thanks

Many coach front cap and grill designs will allow water to enter the airhorn leading to the filter. The filter becomes saturated and the MAF sensor will send a warning. After the filter drys everything is back to normal warning light goes off.
There may be someone out there with your same Newmar model that has a fix. I know on my Airstream I installed weather stripping on the inside of hood at the the top hingline.

Exactly what az bound advised! On our trip to Alaska last year, we drove thru lots of rain and it caused the stock air filter to become wet. I changed it a couple of times but finally it got so wet that the Actia displayed P102. After letting the MAF dry out and clearing the code, we had no further problems. I did change the MAF also, but that was not really necessary.

To avoid future problems with water being ingested into the MAF thru the stock filter, I purchased the Ultra CAI from Brazels and I no longer have to worry about getting water in the MAF.

Bill Healy welcome to irv2.
Here is a thread I started back in 04 and we still have people with problems.
Read it through there are pictures and follow ups as to what I have now.
The bulb gaskets are still there to protect the wiper motor.
