Vehicle specs
Mazda Biante (JDM)
engine: SKYACTIV-G 2.0
Vin CCFFW-101975
Year: 2013
KM: 97,000
Has I stop and manual shifting on Automatic transmission
I have followed the repair manual https://mazdamanuals.com.au/wsm-secure/WSM/D9G6-1A-21B_Ver17/esicont/srvc/html/id0102h9703700.html
current fault is for the CMPS (don't know the fault code) Read as Cam position Sensor bank 1 fault
I have replaced both Cam sensors with new parts and reset the ECU by leaving the battery disconnected for 5+ hours
Fault returns within 15 seconds of the engine starting. Also have lack of power, loss of gas milage, and having to rev 5-6k rpm to be able to accelerate.
When replacing the CKP the vehicle will no longer start. I can place the only CKP back in and the vehicle to start. I have gotten two CKPs from two different manufactures and nether will allow the vehicle to start.
I am very limited with resources at my current location as any mail from the US takes 30 days to arrive and there are no part stores on this base (Closed base). The autoskills shop has the tablet Autel service readers but I can not find the function to relearn the CKP.
Any ideas on how I can get this van back into some kind of worker order given my location?
Thank you

Have you done any of the Diagnostic Procedures in the link that you provided?
When you disconnect the wiring connector from the Cam sensor and switch the Key to ON is there Battery Voltage (12 volts +or-) on connector terminal C? (There should be).
Then, is there continuity between terminal A of the connector and a body ground point? (There shouldn't be) ((If there is then that would be a short to Ground on the signal wire))
Also, with Key ON is there any voltage reading on terminal A? (There shouldn't be) ((If there is then that would be a short to Power on the signal wire))
Then,
-
Intake CMP sensor terminal A and PCM terminal 1YIntake CMP sensor terminal B and PCM terminal 1AC
Not sure if you meant code or cold.
Scotty uses (terrible) dictation software. He probably meant to say if you still get camshaft codes after replacing the sensor, then the timing chain is worn
Well, if you get that cold in your place of sensors, that usually means the timing chain is worn
Yes,
I have gone through the CMP steps, i am down the to CKP in the testing process. When i replace the CKP it will crank but will not start. When i put in the old module to cranks right out but with the lack of power and high rpms needed to gain speed in the lower gears. I have two parts from different manufactures ordered at different times. The autoskills center here has Autel diagnostic tablets but they are not familiar with JDM and nor am I so i can not find the correct way to save the and learn the new CKP.

Not sure if you meant code or cold. This location never get below 75. I have the maintenance records for the vehicle and the per auction inspection for the timing chain to go on a vehicle that only has 60k miles and has been maintained the way this one has without the additional signs like misfires it doesn't seem likely. Now we also have a base wide speed limit of no higher than 35 mph so that could also be a factor. The main issue i am facing at the moment is when replacing the CKP it will not run and the local autoskills has two different Autel systems but the workers an myself can not find the way to learn the new CKP sensor or if it even needs to be learned.
