SOURCE: Auto Diagnostic Trouble Code

cORRECT. tHIS CODE DOES DEALs With emmissions. P1400 deals with the EGR valve. In case u are not aware, EGR stands for Exhaust Gas Re-circulation. What really this valve does is that it re-cycles some of the exhaust gases into the cylinder for combustion. The EGR valve might be blocked or has malfunctioned. It is advised that this valve changed or consult with a mechanic who is knowledgeable about this technology. a malfunctioned/dis-abled EGR system will cause the car to fail an emissions test, and may cause the EGR passages in the cylinder head and intake manifold to become blocked with carbon deposits, necessitating extensive engine disassembly for cleaning. So it is advised that u repair this ASAP

SOURCE: car won't start

check first the ground connections and the terminals if they are loose. Check also the starter relay and its cables. Have the starter capacitor checked. If that does not resolve it go to the starter motor and have it checked.

There are two speed sensors one is called a revolution sensor that is located on the case of the transmission. You can take the driver side wheel off and see the sensor on the top of the case of the transmission. A 10mm bolt is holding it in. Easy fix

Trying to find the reason for code p2000


The scan tool your using is generic ISO 9141 is used as the protocal. Its not a code. kwp2000 is not shown. Try and use it on manufacture specific or try and get any freeze frame codes and reply or repost. ( Don't forget to turn ignition key to the run position when trying to retrieve codes.)

Trouble code 9141


ElmScan ISO is a PC-based scan tool, and our most popular OBD-II interface. It supports the ISO9141-2 and ISO14230-4 protocols used mostly in Chrysler Corporation, European, and Asian vehicles. Be sure to determine the communication protocol used in your vehicle before purchasing this scan tool.
Processor: ELM323, crystal-controlled for accuracy
OBD-II Protocol: ISO 9141-2 and ISO 14230-4 (KWP2000)
Output protocol: RS232
Indicator LED's: OBD Tx/Rx, RS232 Tx/Rx, Power
Operating voltage: 12V, internal protection from short circuits/overvoltages
Dimensions: 3"x4" (76x102 mm)


The interface can be used in conjunction with our free software to turn your laptop or desktop computer into a fairly sophisticated auto diagnostic system. The ScanTool.net program has a built-in database of more than 3000 trouble codes, and allows you to read and erase stored trouble codes and oxygen test results, turn off the MIL ("Check Engine" light), and display real-time sensor data. For more information about the program, please visit our Software page.

P1320 trouble code plus


The P1320 code is essentially a coil primary voltage problem. This is traceable using a labscope or accurate DVOM and perhaps you can isolate one or two coils that still work but are close to failure...but there is a nissan service message recommending replacement of ALL coils with updated/improved models to prevent this type of failure. TCS/SLIP is traction control. Most likely you have a speed sensor issue. Be aware, some vehicles can falsely illuminate TCS because of low tire pressure in a single wheel.
