SOURCE: high idle stalls at lights code for crank sensor

Crankshaft and Camshaft Position Sensors Camshaft Position Sensor Engine timing is determined from the relationship between the crankshaft and camshaft. This relationship is maintained by a timing chain or timing belt. The Engine Management System does not control engine timing but it does monitor the relative position and speed of these shafts by monitoring signals generated by sensors. The Engine Management System (EMS) uses signals generated by the camshaft position sensor to synchronize fuel injection to the valve sequence and for the on-board diagnostic procedure for misfire detection. The EMS energizes the injector at or near the time the intake valve opens. For misfire diagnosis, the EMS compares the number of camshaft sensor reference pulses and the number of crankshaft position sensor reference pulses received. If the EMS receives an incorrect number of pulses Diagnostic Trouble Codes (DTC’s) should be stored in the EMS.
If the camshaft position sensor or circuit is faulty most engines will start. Some engine management systems will then default to a pre-programmed injector firing sequence. All injectors may be energized simultaneously or all of the injectors on one bank may be energized at the same time. If the CMP data is required for misfire detection and reliable CMP data is not present misfire detection would probably be suspended.
Related Symptoms The following symptoms can be caused by an intermittent wiring connection or faulty signal to the EMS:

  • Extended crank time with a cold engine
  • Intermittent rough running
  • Unstable idle
  • Bucking
  • Hesitation
  • Stumble
  • Chuggle
  • Poor fuel economy
  • Stalling on acceleration
Crankshaft Position Sensor Engine speed is a very important input to the Engine Management System (EMS). Crankshaft speed and position are the basis for many calculations made by the computer. Crankshaft position values are transmitted to the computer by pickup coils also known as Permanent Magnet (P/M) generators, hall-effect sensors or optical sensors. The Crankshaft Position Sensor (CKP) also known as engine speed sensor is located in close proximity to the crankshaft.
In addition the EMS uses minute variations in the CKP sensor data to determine engine misfire. The EMS uses this information in conjunction with the camshaft position sensor to perform misfire diagnostics.
Related Symptoms: No Start/Intermittent Start Condition – Can be caused by a faulty crankshaft position sensor due to loose connections, bad grounds, high resistance in the circuit, or opens in the circuit

SOURCE: WHERE IS THE CAM POSITION SENSOR LOCATED ON A 2004 NISSAN MAXIMA

WHEN YOU STAND ON THE FRONT OF THE CAR YOU ONE IS RIGHT BELOW OF THE INTAKE WHICH IS BANK 2 OR THE ONE CLOSE TO FIREWALL , BANK 1 ONE IS ON SAME SIDE NEXT TO THE RADIATOR BUT THEY BOTH ON THE CAM RIGHT SIDE OF THE ENGINE, THE EASIEST WAY TO IDENTIFY THEM IS THAT THEIR CONNECTOR IS GREEN, ONCE YOU LOCATE THEM THE CLIP NEEDS TO BE PUSHED DOWN TOWARD THE SENSOR FOR THE CONNECTOR TO BE RELEASED, ONCE YOU REMOVE THE CONNECTOR THERE WILL BE ONLY A 10MM SCREW HOLDING THE SENSOR PULL IT OUT , THE SAME SETTING THE NEW ONE PUSH IT ALL THE WAY IN , THIGHT THE 10MM SCREW, CONNECT IT BACK AND YOU'RE DONE,BUT FOR THE ONE ON THE BACK SOMETIMES MIGHT BE NECESARY FOR YOU TO TAKE THE INTAKE OFF....HOPEFULLY IS NOT YOUR CASE....



Good luck!!! and if you need the crank for hard starting on hot/warm, it is located on the botton middle section on the transmission is the only cable that goes down to a small piece of metal and it is held by a 10mm screw only to protect the sensor, you will se the sensor once you remove that small about 6-8 inches piece of metal. Then you'll be able to unescrew the 10mm screw that holds the crank position sensor. when you pull it off you'll be able to see the fly wheel inside the transmission...



you all enjoy your rides out htere!!!

SOURCE: 1996 nissan maxima won't start, battery is charged but engine does't crank when I turn key

This might sound stupid but try loosing the gas cap. If you hear a air suction noise its because your gas tank is vapor locked. This happens when your pressure in your gas tank becomes greater than your fuel pump is pumping. What causes this problem is over feeling your gas tank at the gas station. If you fill up and it clicks off.....round to the nearest nicklel. Dont put that extra 25 cent in. Your car is designed to burn fuel vapors as well as gas. When you over fill your tank that extra 25 cents goes down the line attended for gas vapors. In years of time it clogs up a charcoal canister designed to filter gas vapors causing a air lock. And guess what? Your car or truck will just shut off when that pressure is reached. Solution: Replace the canister. Most in older cars are behind headlights. Vans are underneath vehicle. Quick fix: Loosen gas cap...Cars starts immediately..Cheap fix: Drill a very small hole in center of gas cap. This problem shows no service light on. Remember, A car thats broke doesnt work one day and not the next. Vapor locks will let the car start after time of just sitting after the presure drops.I hope this helps someone. And the next time your at gas station ....Tell them to round to the nearest nickel

Twice now my 2004 Nissan Maxima has completely died as I was coming to a stop at an intersection. Both times it started back up again after about 10 minutes and then runs normal. I just don't want to...


I can guarantee your car keeps cutting off because there is a problem with your crank sensor. I have a '04 maxima SE and the day I paid my car off it did the exact same thing, it cut off then cranked back up a short while later and when I took it to the dealer there was a problem with the crank sensor. You might wanna check that and get it replaced soon...it's cheaper if u dont do it at the dealer tho

the cp sensor is big problem for nissan. you can buy one at auto zone for $35 and with a little time and patience you can replace it. i think you might have a crank position issue. the key has nothing to do with it. just bad timing

My 2002 Nissan Maxima hesitates to start


if vehicle hesitates to start do you mean long cranking time (posible fuel pump) or no crank at all then suddenly starts then it is possible starter solenoid (notorious) - complete starter assembly needs replacement.

2003 nissan maxima 3.5


is the check engine light on?? i would suspect your crank angle sensor. replace the cam sensors too. nissan had problem(there is a campaign) with those, so they came out with a crank and cam sensor kits. get the kit ( at a dealer ) and install it. actually have your nissan dealer run your VIN number to see if you don't have open campaign for it, if so, they will replace them for FREE. But that's what I would be looking at if one of those came to me to fix.
