Can EVAP System Result In Power Steering Switch Failure.

Asked by Dec 03, 2012 at 12:40 AM about the 2001 Dodge Durango SLT 4WD

Question type: Maintenance & Repair

2001 Dodge Durango took it to a repair facility and they replaced the evap system some hoses and the canister. A few days go by and then I get the service engine light again. I check the code using the ignition trick and got the code 0551. was wondering if this is a result from the evap system needing things replaced or not. I noticed the high idle prior to the repair of the evap system however the repair shop didn't mention anything about this at the time of their check up...

The P0551 is a "P0551 Power Steering Pressure Sensor Circuit Range/Performance." Could be a bad sensor, a bad pump, bad/power steering fluid or a combo of all that. Clear the code, flush the pump at a service center and add new fluid and then see what she does. If you still get a code, change the sensor. If the pump is bad, the service center won't/shouldn't flush it and should let you know of such. Ask them to check it BEFORE the flush so you don't waste any money if it is bad If you change out the pump, take the opportunity to replace the belt (Goodyear Gatorback). 2000 D's do not have a history of bad power steering units, so you may be okay and it's just a bad sensor or old fluid. My guess is that you possibly have the stock original fluid in there since little other info was given.
