Is there a way to check the crankshaft sensor by ohming it out? My car will crank but not turn over. I have checked all fuses and relays. Can you help?

DTC P0335: CKP SENSOR CIRCUIT MALFUNCTION
NOTE:After each repair, clear DTCs. See CLEARING CODES/PCM RESET PROCEDURE under SELF-DIAGNOSTIC SYSTEM. Turn ignition off and then on. Read DTCs to verify repair is complete. For DLC and PCM connector terminal identification, see CONNECTOR IDENTIFICATION. For wiring diagrams, see WIRING DIAGRAMS.

Using scan tool, read DTCs. If DTC P0335 is present, turn ignition off. Ensure CKP sensor harness and connectors are not damaged and connections are okay. Repair as necessary. If harness and connectors are okay, go to next step.
Ensure CKP sensor is installed correctly. Repair as necessary. Check for damaged CKP sensor reluctor ring on crankshaft. Repair as necessary. If reluctor ring is okay, check for magnetic debris on reluctor ring. Repair as necessary. If reluctor ring is okay, disconnect CKP sensor harness connector. Using a DVOM, check the following:
On 1996-1997 XJ6 and XJR models, check for continuity of White wire between CKP sensor connector terminal No. 1 and PCM Black connector terminal No. 23, and of Orange wire between CKP sensor connector terminal No. 2 and PCM Black connector terminal No. 26.
On all other models, check for continuity of Red wire between CKP sensor connector terminal No. 1 and PCM Black connector terminal No. 23, and of Blue wire between CKP sensor connector terminal No. 2 and PCM Black connector terminal No. 26.
Repair wiring as necessary. If wiring is okay, go to next step.
Check the following:
On 1996-1997 XJ6 and XJR models, check White wire for short circuit to ground at CKP sensor connector terminal No. 1.
On all other models, check Red wire for short circuit to ground at CKP sensor connector terminal No. 1.
Repair wire as necessary. If wire is okay, replace CKP sensor. Clear DTCs. Turn ignition off and then on. Read DTCs. If DTC P0335 is not present, repair is complete. If DTC P0335 is present, replace PCM.
