I've done some digging this morning...(I would like to add I am not "Technical Help" here at Pico)...
From the web...
"P0722 is for Output Speed Sensor 2 Circuit No Signal. This means that the transmission control module is not receiving a signal from the Output Speed Sensor. There is a possibility it could be the Neutral safety switch. They can get dirty and cause problems."
Testing Neutral Safety Switch
Neutral safety switch location (component location)
Locate the neutral safety switch
Disconnect the wiring connector at the switch
Test for power at the wiring harness with the key in the "engine crank" or the gear shifter in the "reverse" position. (do not start the engine)
If power exists reconnect the neutral safety switch and probe outgoing wires at the connector.
If no outgoing power is present the switch has failed and needs to be replaced.
If the engine will not crank over with the car in "park" push down the brake pedal and try cranking the engine over with the car in "neutral". What you are doing is bypassing the "park" position in the switch and now are using the little used neutral circuit. If in neutral the engine starts the switch is probably bad.
Tip: Sometimes a neutral safety switch can become misadjusted. This switch adjustment can change due to normal wear of mechanism that controls switch slider.
Other complications can occur if there is a loose connection somewhere in the system. While this condition is not a shorted circuit problem, it is a condition that simply breaks the flow of electricity intermittently.
Also an interesting article here - http://www.underhoodservice.com/issue/a ... tid=105757
I believe we should be seeing a square wave (hall effect) from your sensor (from the above article as you have 3 wires I am guessing its a 'MagnetoResistive Sensor'). Currently it looks more like a camshaft signal....
I think a shorter test will provide a better sampling rate across the screen and therefore we should see a square wave signal,....
There is clearly 55 seconds of "faulty signal" in your bad waveform...but identifying the cause for this is important.
