Code P0330 ( CKP sensor) ,what is that on Nissan almera 1.4

egr IS DEAD FIX EGR VALVE FIRST.
EGR DEAD CAUSES PING, HEARD OR NOT IT IS THERE.

MOST CARS THIS OLD THE VALVE IS BAD, OR JAMMED
OR IS PACKED UP FULL IN CARBON OR WORSE THE WHOLE
EGR PATH IS CARBON BLOCKED.

KNOCK 2 SENSOR LOSE? OR WIRES TO IT WRECKED.

what a great question!
no year told, no country , no car told just raw engine
QG18 comes in many types QG18DD,,1999 to 04
QG18DE, 1999 to 2007 QG18DEN is the natural gas version?

lacking all key facts.
I go GENERIC (full bore)

the answer is super simple..
causes spark misfire. (and scanned PCM see P03xx errors DTC)

loss of engine horse power. and wasted fuel.
or engine dead. fully and no spark at ALL.

why worry it at all.??? if scans are clean this is it if CKP does not trip CKP errors DTC

must we guess all of these and if yes why?
and more,

The QG18DE is used in the following vehicles:

• 2000-2006 Nissan Sentra B15 and N16
• 2000-2005 Nissan Pulsar N16
• 1999-2002 Nissan Primera P11.144
• 2002-2007 Nissan Primera P12
• 2000-2006 Nissan Almera N16
• 2000-2006 Nissan Almera Tino
• 1999-2006 Nissan Primera
• 2000-2006 Nissan Expert
• 1998-2006 Nissan Avenir
• 1999-2005 Nissan Wingroad/AD van Y11
• 1999-2005 Nissan Bluebird Sylphy G10
• 1998-2004 Nissan Sunny B15
• every one sold in USA all scan easy as eating cherry pie !

the CKP and CMP sensors are the base line inputs for all spark and fuel injections and timing and timing advance of spark
if spark dies the PCM cuts all fueling dead( no crash&burns)

Clean Throttle Body and MAF. Check for DTC trouble codes.

You will need to get a Good Mechanic to look at this. There are 3 completely different problems here so it will need to be properly checked out. I've listed the Trouble Code definitions below.
-The knock sensor looks for signs of the fuel igniting at the wrong point in the sequence.
-The Crankshaft position sensor checks the pistons are in the correct position for the engine electronics to be in the correct sequence.
-The Air Control system is a set of valves that adjust air flow through the engine when running at different speeds. (Slow needs less air, fast needs more air).
Knock Sensors and Crankshaft Position Sensors can be in some ridiculous places on an engine and usually need major surgery to get to them. Air control systems could be anything from a 'sticky' valve to a faulty sensor.

P0325 = Knock sensor (KS) 1, bank 1 - circuit malfunction
P0335 = Crankshaft position (CKP) sensor - circuit malfunction
P0505 = Idle Air Control System

run the fault codes and look for cam/crank position sensors.
faulty or loose connections may cause this fault. If you have more than 1 key in the ignition then it has been known that the mass of swinging keys will switch off the ignition
(current recall on all GMC ignition switches for just this reason)

You have an incredible amount of codes, so I would look for a abrasion in the wiring harness.

Code 345 means the cam sensor on bank two is not sending the correct signal to the engine computer. So no spark.
If you have replaced the sensor, the problem could be the cam or the wiring from the sensor to the computer.

P0725 NISSAN - Engine Speed Signal

The P0725 Codes is triggered when TCM does not receive the engine speed signal from ECM.

The Engine Control Module (ECM) monitors the engine speed through the Crankshaft Position (CKP) sensor with the engine running, and send signal to the Transmission Control Module (TCM).

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)

Possible causes:
- Open or shorted CKP sensor circuit condition
- Poor CKP sensor electrical connection
- Check communication error between the ECM and TCM
- Failed CKP Sensor

Possible solution:
Very common problem with Nissan vehicles, usually replacing the Crankshaft Position sensor takes care of the problem.

Keep us updated.

P0330 Knock Sensor 2 Circuit Malfunction (Bank 2)
Check the resistance of the knock sensor (compare it to factory specs)
The knock sensor is faulty and needs to be replaced.
Check for broken/frayed wires leading to the sensor.
There is a wiring short/fault in the knock sensor circuit
Check timing
