If the crank sensor has been replaced and is getting signal then inspect the sensor wiring for damaged wiring or connector pins causing a loss of signal to the PCM

Plug in with a scan tool that reads live data and watch for RPM signal
Customer: replied 9 months ago.
It is not getting rpm signal on scan tool.
Expert:  Daniel Wilson replied 9 months ago.
Thanks for the info. Either mechanically the sensor is not reading or there is a wiring issue between the sensor and PCM
Customer: replied 9 months ago.
Could the can sensor be an issue or will it throw its own code?
Expert:  Daniel Wilson replied 9 months ago.
Cam sensor could also cause this code to throw. Click this link for the PCM pinout diagramPCM Pinouts
Expert:  Daniel Wilson replied 9 months ago.
the crank sensor has three wires to confirm are good signal to the PCM, B+, Ground, and signal. The pin locations are in the link I posted
Customer: replied 9 months ago.
There isn't anything but autozone at the link.
Expert:  Daniel Wilson replied 9 months ago.
when I click on it it works.... Look at the center of the page.It is there ..... autozone has schematics
Customer: replied 9 months ago.
If I check for power, signal, and ground and it dosent have it what do I start on? The wiring?
Expert:  Daniel Wilson replied 9 months ago.
Yes that is correct. Test for continuity between the sensor and the PCM for a break in the wiring
