DTC P1331: Low reliable dynamics of correlation of CKP-CMP sensors

malfunction, more often the deflection of the main shaft / knock position sensor effects: sudden engine run out (also while driving),
impossible to run on warm or problems with running hot / hot – on cold piles normally

• Possible reasons
• Low fuel level or fuel quality
• Mass flow sensor (MAF) failure
• Low fuel pressure
• Incorrect engine reset or faulty knock sensor Faulty knock sensor The sensor sensor harness is open or shorted
• Knock sensor circuit poor electrical connection
