 Subject: P0551 Error Code
IP: Logged
Message:
I have a 2000 Dakota 4.7 engine.
Recently, the check engine light came on, and when I do a diagnostic svan, I get error code P0551, Power Steering Pressure Sensor CKT Range /Performance.
Anyone seen this one before, and if so, what is the fix ?
Thanks in advance.
Steve

Check your power steering fluid level. If it is a little low, find the sensor on the high pressure power steering line, if it's leaking change it as soon as possible.
The reason I suggest changing it a.s.a.p. is because the fluid will eventually travel down the wiring harness to the O2 sensor connector on that side of the engine and cause trouble and could even short out the O2 sensor.
This problem had been discussed on here before.

I had this on my 2000 Dakota. Went to Autozone and purchased a power steering pressure sensor for 32.00. It was right under the hood next to the power steering fluid reservoir. I sprayed some WD-40 on the old sensor a couple of days before I put the new one in. You need two wrenches....one to hold the hose fitting from turning and one to loosen the old senser. Unplug the wire adapter then unscrew the old sensor. Have a rag available to catch any power steering fluid you lose...it will be small amount. Screw the new sensor on and reconnect the wire adapter. You will then need to bleed the power steering hose. To do this have the cap off the power steering reservoir and fill to the cold line. Start the engine and turn the steering wheel from left to right avoiding the stop wheel. Let the engine get to operating temperature and fill ps fluid to hot mark if needed. Replace reservoir cap. Your P0551 error should go away in the next couple of days if this did the trick. Mine went away the same day after a few starts.
