mlebioda Posted August 8, 2005 Share Posted August 8, 2005 I have a 2000 Outback (91,000 miles) with a PO325 Knock Sensor Code. I changed my spark plugs, ingintion wires and PCV at 75,000 mile with Subaru parts. What are my next steps. If I need to order a new sensor what is the part number? What are the instructions to change it? Thanks Link to comment Share on other sites More sharing options...
B99Brighton Posted August 9, 2005 Share Posted August 9, 2005 What motor is it? I know the knock sensor on my 99 2.2l isunder the drivers side intake manifold. It is held in place with one bolt and takes 5 min to change. Not sure on a 2.5l. I had mine fail a couple of years ago. Sorry i don't have a part #.

Cougar Posted August 9, 2005 Share Posted August 9, 2005 Here is what the code definition is: Knock Sensor 1 Circuit Malfunction (Bank 1 or Single Sensor) . You do need check the wiring to the sensor for a connection problem and probably replace the sensor. This is a dealer only item. They will know the right one you need from the year of the car. When installing a new one, do not over torque it. Link to comment Share on other sites More sharing options...
mlebioda Posted August 10, 2005 Author Share Posted August 10, 2005 Thanks for all your advice. I went to the Subaru deal and was able to get a "Sen Assy-Knock" #22060aa070 for $95. I found it on the drivers side by the maninfold. It took me about 10 minutes to install after the engine cooled down. Thanks again, Link to comment Share on other sites More sharing options...
mattocs Posted August 10, 2005 Share Posted August 10, 2005 I think my knock sensor was $22 at Autozone. It took about 3 minutes to install. Good luck! Link to comment Share on other sites More sharing options...
jcrowley Posted August 10, 2005 Share Posted August 10, 2005 Help! I have a 99 legacy L wagon (2.2l 5sp manual) and the CEL is on w/acocmpanying noise that is new. Took it to mechanic who said it's the PO325 Knock Sensor Code - sent me to dealer. Dealer said it's d/t timing belt tensioner and wanted to charge me about a grand to fix it. Took it back to my mechanic who changed the timing belt and tensioner (for 1/3 the price) but didn't replace the sensor - b/c the engine noise wasn't fixed (but had improved). My mech recommends either selling the vehicle OR having a new (to me) engine put it. Any thoughts?? Thanks Did also contact CCR Inc @ this Link to comment Share on other sites More sharing options...
