Just got my engine washed. Now my crank case pressure light sensor came on??? Help

Probably just need to change the filter. Shouldn't be a big deal.

 

Its things like this that I never let anyone power wash the engine. All of that wiring is not designed to withstand that much pressure.

 

Disconnect the sensor, blow out the connector and plug it back in. I also think the code is from water intrusion into the terminals.
The sensor is item 16 of the drivers side view;

filter is on the drivers side at the front close to the top of the engine,,it is about 10 x 10 in. it might be behind the power steering reservoir , has about 10 screws holding it on ,,, let you engine dry out,,the sensor plug just got wet,,BTW the filter cost about $65. If your check engine light won't go out disconnect your batteries for about 2 mins and then reconnect,,it will reset your ECM

 

If you fix the actual problem, i.e. get the water out of from where ever it is that caused the code in the first place, the code should go inactive on its own and the truck should run fine.

 

What's the service interval on those.......?


P.S. I wash my engine (myself) weekly with a garden hose and simple green, power wash 3-4 times a year.....

Just stay away from the ECM .....
