Check Engine Light

[Wolfgang]

Recently I had the DTT VB installed in my truck. Ran around for three days in town and then took off for a trip up the Oregon Coast. 30 miles out of Reno the Check Engine Light comes on. The light stays on until I get to Eureka California and I quit towing. Ran around for a few days (light off). Hooked up and went up to Astoria, Light came on 10 miles down the road fom Eureka. The long and the short of it is my check engine light comes on when ever I tow. As soon as I stop towing it goes off. I read the codes by turning the key off and on three times. They were as follows.

Your new VB Pressures are higher than stock, probably time to add a resistor .
