hi guys and gals 2005 mazda 6 2.3 auto. code 340 cam sensor replaced it and crank sensor still no start cranks fine no spark no injector pulse and the security key flashing. will the security cause a no spark no pulse? cam code threw me a loop and the chain and cam align is ok.

 

DTC P0340 CMP sensor circuit problem

DETECTION CONDITION
• The PCM monitors the input voltage from the CMP sensor when the engine is running. If the PCM does not receive the input voltage from the CMP sensor while the PCM receives the input signal from the CKP sensor, the PCM determines that the CMP circuit has a malfunction.
Diagnostic support note
• This is a continuous monitor (CCM).
• MIL illuminates if the PCM detects the above malfunction condition during first drive cycle.
• PENDING CODE is available if the PCM detects the above malfunction condition.
• FREEZE FRAME DATA is available.
• DTCs are stored in the PCM memory.
POSSIBLE CAUSE
• CMP sensor malfunction
• Connector or terminal malfunction
• CMP sensor is dirty
• Short to the power circuit between CMP sensor terminal B and PCM terminal 2S
• Short to ground circuit between CMP sensor terminal C and PCM terminal 2AM
• Short to ground circuit between CMP sensor terminal B and PCM terminal 2S
• Open circuit between CMP sensor terminal A and body ground
• Open circuit between CMP sensor terminal B and PCM terminal 2S
• Open circuit between CMP sensor terminal C and PCM terminal 2AM
• Both CMP sensor wires are shorted to each other
• CKP sensor pulse wheel malfunction
• CKP sensor misinstallation
• Timing chain misinstallation
• Loose timing chain or improper valve timing
• Loose camshaft sprocket lock bolt
• Loose crankshaft pulley lock bolt
• PCM malfunction

 

thanks reaper have a goodday eh
