My truck threw this code on way yo work today startled to miss put new sensor in seems to clean the misses up egsy causes these to go bad

Your lucky if it was just a bad cam sensor, I have seen injectors and also camshafts cause that code to set. The sensor is a cheap fix if that fixed your problem. Crank and cam are same sensor if you swap them and truck then sets a crank signal code then you know it is the sensor. Or you can check the resistance of sensor it should be between 900 and 1100 ohms between pin 1 and 3 or between the (F855) 5-Volt Supply Circuit and the (K44) Cam signal Circuit at the cam sensor connector.

The truck was driving normal then it misses and we change out the sensor back to normal now. Is there a way to check the injectors by a insight without pulling them

There are two tests that can be done using wiTECH. These tests checks both low and high pressure fuel system. Fuel System Run Up test procedure.
This test will take approximately 270 seconds to complete. The PCM will cut out each individual Fuel Injector three times and calculate the delta RPM change. Based on the delta RPM change, the test will indicate a bad cylinder based on the limits that have been set. When the test is complete, the engine will return to idle. This test routine should also be used to validate that the system is operating properly after the repairs are completed.
High Pressure Fuel System diagnostic procedure.
The High Pressure Fuel System test is a comprehensive fuel system test that operates the engine and fuel system under several diagnostic operating conditions. When the test is complete, the engine will stall. In MOST cases, this test can determine IF there are any fuel system issues, and if so, whether diagnostics should begin at the LOW pressure side or the HIGH pressure side of the system. Based on the results of the test routine, you will be directed to either start testing at the low pressure side (step 5) of the system or go directly into the high pressure side of the system in order to shortcut the diagnostic time. However, if the test routine fails and you are directed to the high pressure side of the system and do not find an issue at the completion of the test, it is recommended that you go back to test step 5 and continue with the rest of the fuel system testing. This test routine should also be used to validate that the system is operating properly after the fuel system has been diagnosed and repairs are completed.
