Aloha! New to jeep ownership and new to this kind of online greatness. I own a 2002 4cyl automatic se. I just purchased the vehicle a month ago and two codes have popped up. One for p0551 and one for p0320. 0320 is for crankshaft position sensor, so I will replace that tomorrow. P0551 is for power steering sensor? What's the deal with this? I cannot find the part anywhere for my year and model! Anyone have any helpful thoughts?
