DTC P0340: Notes

2010 Mazda 5 Sport, 2.3 L, StandardSECTION Notes
DTC P0340 [L3] DETECTION CONDITIONS AND POSSIBLE CAUSES

DTC P0340 CMP sensor circuit problem
DETECTION CONDITION 
  • The PCM monitors input voltage from the CMP sensor when the engine is running. If the CMP sensor signal timing inferred from the CKP sensor signal has deviated, PCM determines that CMP circuit has malfunction.
  • Malfunction is detected in the input pulse pattern from the CMP sensor.

Diagnostic support note 
  • This is a continuous monitor (CCM).
  • MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
  • FREEZE FRAME DATA (Mode 2/Mode12) is available.
  • DTC is stored in the PCM memory.
POSSIBLE CAUSE 
  • CMP sensor connector or terminal malfunction
  • 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
  • Both CMP sensor wires are shorted to each other
  • PCM connector or terminal malfunction
  • 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
  • CMP sensor malfunction
  • CMP sensor is dirty
  • CKP sensor misinstallation
  • CKP sensor pulse wheel malfunction
  • Timing chain misinstallation
  • Loose timing chain or improper valve timing
  • Loose camshaft sprocket lock bolt
  • Loose crankshaft pulley lock bolt
  • PCM malfunction

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
