He meant Coolant Temperature Sensor.

Sounds right...

Re: How to test the Crank Angle 1 & 2 and Cam Angle Sensor.

Here is the scope image of a good cam sensor plan to change to a bad one and see if anything shows up.

Re: How to test the Crank Angle 1 & 2 and Cam Angle Sensor.

Hey I'm also having no luck finding which sensor in the car isn't working properly... I check codes regularly but nothing.


1----
Twice in the last 9 months I have started the car in the morning and everything is perfect and about 2 minutes into driving the engine vibrates like crazy, revving it feels like it's going to ruin the engine. I stop and start the engine and it's still there.... After a few start and stops everything is perfect again. (I've read something once about one side of the engine shutting down is this related?)

2----
If I start the car in the morning everything is perfect.
If I turn off the car after completely warmed up and start it straight away it's perfect.
If I turn off the car and come back 2 hours later and start the car the engine keeps on turning over and over and eventually starts.

Any suggestions?
Have changed coolant temp sensor and gauge temp sensor (the one just above the coolant temp sensor. After installing them a few months ago I disconnected the battery.. left it disconnected overnight to reset everything

Thanks, Jordan.

Re: How to test the Crank Angle 1 & 2 and Cam Angle Sensor.

I had one of those sensors go bad on my 92. The car wouldnt start, period. I picked up all three out of a wrecking yard car, put them all in, and it started right up. I have no idea which one was bad.... Codes said two of them were. I priced them new, and omg... $250 a piece, if you can even find one... So stupid...

Did you ask Brooky, two of the sensors are the same so if you get one you can swap them over. My guess is the cam sensor near the battery.

Re: How to test the Crank Angle 1 & 2 and Cam Angle Sensor.

Hey I didn't ask brooky because both cars had no engines and wiring harnesses... I just assumed they had been bought by someone else already, might still be worth giving them a call

Are the cam and crank sensors shared with any other Subaru?

Thanks for the help guys!!!!!

The cam and one of the crank sensors are the same as the Liberty units, the other crank sensor is SVX only.

Re: How to test the Crank Angle 1 & 2 and Cam Angle Sensor.

Okay finished the testing to see if a difference appeared on a bad crank or cam sensor showed up on a scope. The good news is it does. What happens is the sensor still sends a signal but wave pattern is not were it should be as regards timing. I also sprayed freeze spray on the sensor when it was cold and the wave form moved out of aligment. If you have a look at the two images you will see one is clean and the other has a ghost wave, it is the bad sensor.

Re: How to test the Crank Angle 1 & 2 and Cam Angle Sensor.

So, you've confirmed that a 'scope is mandatory to determine if the crank angle and cam angle sensor are bad (?)

Re: How to test the Crank Angle 1 & 2 and Cam Angle Sensor.

yes. The scope can pick up the problem when the ECU doesn't. Also you can test the knock sensors. Its surprising how bad the signal can be and the car shows no major signs.

Check your battery cables for corrosion. The negative cable on mine had the body ground mounting point corroded to the point nothing much passed. The battery end of both cables were terrible too. I think the sensors start to read really screwy when you say have a .5 V drop from the engine/ecu to the battery on the negative side. More so since corroded cables will have a non-linear response to increased load.

This will give you a clean baseline to start with on your sensors and infact checking the ECU ground seems to be Subarus #1 thing to recomend in troubleshooting anything dealing with the engine

Hey thanks a lot for the tip im looking into that, I really wouldn't be suprised if that's what it is as well as crank and cam angle sensors.
