Wells Nissan P0507 Relearn Cam and Crank Sensor location and Testing

http://www.wellsve.com/ This video will locate and test the cam and crank sensor on a 2004 Nissan. It will also demonstrate an alternative method to relearn the idle air control. When a P0507 or a high idle occurs after a throttle body clean, the TSB requires the use of the factory (Consultant II) scan tool to reset idle air control. The reset can also be performed by following the steps in this video, without a scan tool.

2003 Nissan Altima S - Camshaft & Crankshaft Position Sensors
2003 Nissan Altima S 2.5L W/Automatic Transmission PROBLEM: INTERMITTENT NO-STARTS & ROUGH-STARTS WITH NO DTCs SET. A LOCAL AUTOSHOP HAD REPLACED ONLY THE CAMSHAFT POSITION SENSOR, MADE SURE NO DTCs PRESENT AND OPS CHECK GOOD. HOWEVER, THE PROBLEM RETURNED. NOW, THE SAME AUTOSHOP BELIEVES THAT THE FAULT IS WITH THE TRANSMISSION FLEX PLATE, WHICH MAY HAVE DAMAGED THE CRANKSHAFT POSITION SENSOR AS WELL, ACCORDING TO HIM. ESTIMATE IS AT ~$750. The mechanic didn't try to replace the Crankshaft sensor alone, he went straight for the Tranny drop. I figured go with the cheap fix first. If it comes back, then we will look into the Flex Plate. I replaced the recently replaced Camshaft sensor & the never been replaced Crankshaft sensor. So far, so good. Replacing the Camshaft sensor is a 2-minute job. The Crankshaft sensor will likely take 30 times as long. It seems like the Old Crankshaft Position sensor I removed was a bit high on a resistance check, when compared to brand new sensors. With too high a resistance value, the sensor may not make use of the full voltage it is receiving and/or it may not return the required amount of voltage to the Powertrain Control Module (PCM), which will lead to irregular engine operation or a no-start condition. Both Camshaft & Crankshaft sensors are the same part number. The 3rd version of the sensor is encased in metal, not plastic. The OEM part number is 23731-6N21A ($44 us) The old part numbers were encased in plastic. These part numbers should not be used: 23731-8J005 & 23731-8J006 FOR ONLINE PART PURCHASE: http://www.nissanpartszone.com/components/2003-nissan-altima_engine-control -module-226-12.html "DIGITALDXING" PROVIDED THE LINKS LISTED BELOW AND POSTED SOME PICTURES (2003 NISSAN ALTIMA 2.5L) http://x.nissanhelp.com/forums/members/digitaldxing-albums-2003-nissan-alti ma-crankshaft-position-sensor-picture331-2003-nissan-altima-crankshaft-posi tion-sensor.html#picturecomment_19 "PAUL" POSTED HIS PICUTRES HERE (2002 NISSAN ALTIMA 2.5L) http://www.paulstravelpictures.com/Nissan-Altima-Camshaft-Crankshaft-Sensor s/ "DENTNSHELL" POSTED HIS FIX HERE (2005 NISSAN ALTIMA 2.5L) http://dentnshell.com/Projects/2005Altima/CamkPosition.html "MULEMAN" POSTED A GREAT STEP-BY-STEP WRITE UP WITH PICTURES HERE (2006 NISSAN ALTIMA 2.5L) http://www.nissanclub.com/forums/f-q-2002-2006/286857-diy-crankshaft-positi on-sensor-cps-2006-2-5-altima.html Thanks a bunch, muleman. ...ACTUALLY, THAT WHOLE THREAD AT NISSANCLUB.COM IS A GOOD READ. Yahoo! Answers Best Answer - Chosen by Voters Nissan recalls that problem to reprogram the ECU. What happens the crank sensor electrical terminals seep oil into the crank sensors plug. The new metal crank sensors correct this problem. Location of this sensor on the back of the motor is difficult to change and you need gorrilia finger grip to depress the connector green lock and remove the sensor. Depending on your cars Vin# Recall Campaign # R0712 NHTSA# 07V-527. Hopefully your factory warranty replaces the sensor no charge 5yr/60,000 mile. The campaign only covers the ECM reprogram. The ECM reprogram makes both sensors act as one so either will allow the car to start. Stalling and not starting is a safety risk.

How to diag 02-06 Nissan SES light
**NOTE** This process can be tedious and nerve racking because it may not work up to 20 times or more, if you're not familiar with the timing. Nissan's time windows for each step are very narrow, so if you're not getting it at first, perhaps you need to do it faster or slower and you'll eventually do it right. This video is a tutorial on how to diagnose why your 02-06 Nissan is displaying the SES (service engine soon) light by using your cars built in OBD (on board diagnostic) system. I have a 2003 Nissan Altima 2.5S. It has been confirmed to also work on an 06 Sentra SpecV, 09 Infiniti G37, 08 Patrol 4800 VTC, 03 Sentra GXE 1.8L, 11 Cube, 06 G35, as well as a 350z.

1998 Nissan Maxima with nasty sounding rattle
EDIT: I still don't know exactly what the problem was but the end result was I had a local shop install a newer used engine (VQ30DE) which wasn't too expensive to have done. Good luck to anyone else having a similar issue! Other than this rattle my car has been in fine working order. I have done all of the preventative maintenance. It has 180,000 miles and started making this rattle sound only a few minutes after I drove over a small flat object with my tire. My car has a timing chain that uses a tensioner to keep it from having too much slack but those tensioners can fail from time to time. Before just replacing parts here and there I would like to have some other people's perspectives on what may be causing this noise. Any suggestions would be greatly appreciated. Also, it spit out two codes: 0608 - Cylinder No. 1 misfires (many possible causes listed but I wouldn't be surprised if one of my injectors went bad as 1 or more of them have been making more and more noise over time). 0304 - Knock Sensor; an excessively low or high voltage from knock sensor is entered to ECM; possible causes include short in Harness or Connectors or a bad Knock Sensor. Possible causes I can think of: -Rod knock -Bad rod bearing -Foreign object in valve train -Bad timing chain tensioner -Bad sensor which could be the camshaft position sensor, the crankshaft position sensor, the knock sensor, or an oxygen sensor. -Bad fuel injector
