How-to: diagnose a P0320 (crankshaft position sensor circuit failure)
This si a how-to video on the correct diagnois of a P0320 as applied to jeep/dodge/Chrysler cars and trucks. this was done on a 1997 jeep wrangler 2.5l 4 cylinder engine. you car or truck may not be exactly the same but the theories and principles are the same for the overall diagnosis. if you have any questions please feel free to email me email@example.com, tweet at me @thejeepdoctor, find me on facebood facebook.com/itsthejeepdoctors and please check out my other videos. thanks!
1997 Dodge Grand Caravan cold start. The van hasn't been started in 10 months. The tempreture is -1 digrees cecius. The van has a 3.3L engine.
Stabbing a Ford Cam Sensor without the special tool.
This being the only time I will probably ever stab one of these, I just could not justify the cost of the special tool. Knowing it was essentially a distributor that told the PCM when the engine was at top dead center, I used a little common sense and another Ford, that uses the same sensor, to verify.
neon problem PLEASE HELP
fuel gauge doesnt work the motor is fully built... the gauges go crazy and its extremely anoying plz help
2003 Nissan Altima S - Camshaft & Crankshaft Position Sensors
2003 Nissan Altima S 2.5L W/Automatic Transmission
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

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.

*This video is an EXPERIMENT I wanted to try on my car, and is for INFORMATIONAL purposes ONLY. This fix is for off-road use. The content shown in this video is not intended to encourage emissions test cheating. I enjoy the process of testing theory because you always learn something new, regardless of the outcome.
Using a spark plug defouler kit, I install a "buffer" in between the downstream oxygen sensor and the catalytic converter. Quite often, frustrated car owners get the P0420 code for reasons other than a bad cat. I have heard of people getting the code just because they removed the converter and reinstalled it. It can also happen if you run your vehicle out of gas etc... etc...
It is also common for car owners to get the P0420 code, replace the converter, and both o2 sensors-- only to have the code come back after 1000 miles or so. This can be a very frustrating, time consuming and of course-- expensive venture. Here is one way to resolve the issue. Good luck and have fun!
Dodge Intrepid 2001 2.7L Engine problem (Solved)
My engine started acting this way sometimes. So the "Check Engine" light is on and the engine will not beyond 3000 RPM even when I am driving. Sometimes it will even stop while driving or when I stop at traffic lights.
** Update: I got help from dodgeforum.com and also after checking the PCM error code and it was a faulty "Camshaft Position Sensor" got it for $35 and replaced it myself in like 10 minutes, and the car is working fine again :)
Ignition switch repair Plymouth Neon
Ignition switch actuator pin. Napa PN is 6201414. The MFR part number is 924-704 (Dorman) thanks user "countdingo" for looking this up
Here is a quick vid on a Plymouth neon that had a no start issue, turned out to be a broken mechanism for the ignition switch; in this clip I will be removing the multifunction switch, therefore that will be covered as well. the dodge neon uses the same process
2001 Dodge Dakota 3.9 V6 stall problem
This is a video description of what my 2001 Dodge Dakota 3.9 V6 automatic is doing. It started to stall a month ago and i thought it was just a fluke. Then it happened once a week, then daily, and not it happens a few times a day. I have read many forums about it, Changed the IAC valve, and Crank position sensor. Checked MAP and TPC and both checked out fine. Other options is fuel pump or filter, though both are in the fuel tank. Havent been able to check cam pos sensor, but i would think that i would be having other problems than this stall issue if some of those other things are going out. Any ideas befor i take it to the shop?

IMPORTANT: The crank sensor input signal is the most important signal in a modern vehicle. Without it the engine will not start. The crank sensor measures crankshaft position and rate of change. The ECM then synchronizes this signal to the CAM sensor and determines injection pulse, timing, fuel delivery, idle speed and everything else needed to run the engine.
