Nissan altima 03 p1574


You may want to check with the dealer on this one.
The code means the computer is getting two different vehicle speeds from the two sensors it uses.

2002 nissan Altima SL, check engine light is on, code p0720 & p1574, my car will suddenly rev up to redline or rev up sometimes. This happens twice in the past two months, both when drive in hot...


The problem with the codes yoy have that the real only way to be positive is to have the diagnostic equipment to diagnose it for sure. I can tell you through experience the most possible cause is going to be the transmission control module (TCM) or the revolution sensor but would hate for you to just start replacing parts. It is possible that heat can cause this problem to be worse and if you are in high humidity it is highly possible. Below I have given you some of the information on your codes and the possible causes. I did not give you the testing procedures because you would need the computer equipment to be able to do it. If you want all that information I will be happy to email it to you, just let me know. You can email me at csautomotivecars@att.net with all your information and I will be happy to email you back what I have. This information is directly from the factory service manual for your vehicle. I hope this helps in some way and good luck.

I have Nissan Altima 2002 its working perfect and nothing wrong with the transmission or any things except i just received check engine code P1574 and 0720 together but no thing wrong with transmission...


This is going to be harder for you due to the fact that you most likely do not have the computer diagnostic tools to properly diagnose the problem. There is good news though. In my experience with this in nissans about 95 percent of the time it's a bad speed sensor. As long as you have a good ohm meter you will be able to test it yourself. If it tests out good then you may need to take it in unless you are able to track down the wring short or problem which in worse case it's the ECM. The P0720 is basically telling the computer to let you know there is a problem and tells the ECM to turn on the MIL (engine light, malfunction indicator light). The P1574 like I said in most cases it's the speed sensor. Below I took some snapshots out of the factory service manual for your vehicle. two of them are a description of the DTC's (diagnostic trouble codes) you pulled from the ECM. The other snapshot is how to test the speed sensor without any real fancy equipment to where you are able to just use an ohm meter to check resistance. If the ranges are off then you need to replace the sensor which if I was a betting man would say that's your problem but always test before you start spending money for nothing. I do have the factory service manual for your vehicle I use for my business, so if there is anything else or you had trouble understanding what I am trying to say, feel free to email me at csautomotivecars@att.net with detailed questions so I am sure to try and send you the information you may need. One major factor with your vehicle is you need special equipment to diagnose a lot of things including this but like I said I have seen this many times and this was the cause and with just some basic tools (ohm meter) you can check that yourself. I hope this helps you and good luck.

Where do I find speed sensors on a 2003 Nissan Murano?



P1574 is the ASCD Vehicle Speed Sensor so it would be relative to your speedo problem.

P0720 is the out put speed sensor, And the sensor is going to be towards the out put shaft to the axle. 
Good luck and hope this helps.
