Glen (Cougar) I did an ohms test on the wiring harness that is under the intake manifold. I disconnected the lead that further connects that harness to the ECM. When I did the ohms test on the camshaft sensor leads. I read .2 -.3 ohms resistance on the wiring harness only. Starting to sound like a bad harness.... I'll try the test to bypass the wiring harness for the camshaft sensor. Just a note, but I did the same test for the Crankshaft sensor. Got 00.3 ohms there.... on both leads. Tomorrow I have a few things to test.. I'll let you know.. Thanks... Dan

Yep.. I'll make two long leads and put it from the camshaft sensor to the proper leads on the ECM connector.. Yes.. I put one lead (black) from the ohms meter and connected it to the correct wires on the ECM Connector and then the red one to the end which connects to the sensor it'self. So... From those two points... the .2 ohms resistance. It is a solid reading too. No fluctuation in the meter.. I am thinking that when I took the harness off of the intake manifold and cleaned it I probably did something.. So If the by pass test works.. I'll buy a new harness ..... Dan In Chicago

For Frag; So let me clearfy this. I should check the cam shaft sensor connector to the ecm ? I know the schematics say 28 & 7 but actually it's not.. I trace them out and found out to be different. number 28 on schematic is actaully #2 and #7 is actually #70. When I tested it was .2 ohms resistance.. what does this mean? Problem? if shorted what to do...? same for the crankshaft sensor. ohms out from the connector for the sensor to itself.. to the ecm connector at .2 ohms... Again is this bad..? If so How to correct ??? If shorted out.. Maybe I need to buy a new wiring harness (the one that goes or is attached to the intake manifold. The wires inside the engine compartment were just cleaned and I put new tape on them to better protect them) cost ... @ 156.00 USD... What do you think ? Dan (Chicago)

The cam sprocket does have the little metal tabs in it. It's OEM, so I hope that its' correct. Also checked the ohms on both the crank and cam sensors. Suppose to be around 1,000 - 4,000 ohms and reads about 1,900 - 2,015 ohms. So I am assuming it is correct. Have never looked at the cranksprocket to see how close it is... Never thought about that one because only goes on one way and I figured,, has to be on there right. I'll check that one next.... Thanks Dan

Greetings fellow Subaru Owners: I have just rebuilt my 96 subaru outback EJ25 2.5L engine. It had leaking head gaskets and I had to pull the engine and replace all. Since I had it apart I put in all new bears, cleaned the pistions,, new rings, oil pump, water pump, all new gaskets, new ignitor, new spark coil, new Intake camshaft sprocket on left side, new crankshaft and camshaft sensors, all wires checked for proper ohms and the list goes on.. We'll to the point.. No Start !!! No Spark !! Computer keeps coding a P0340 or camshaft sensor circuit malfuntion. I even replaced the computer.. So anyone have any ideas? Please help if you can..
