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.)

I have a 1998 Nissan Maxima GLE, I Failed the Emission Inspection (DTC) Diagnostic Trouble Codes of "P1492","P1105" What these Codes exactly? mean


A code P0300 may mean that one or more of the following has happened:
  • Faulty spark plugs or wires
  • Faulty coil (pack)
  • Faulty oxygen sensor(s)
  • Faulty fuel injector(s)
  • Burned exhaust valve
  • Faulty catalytic converter(s)
  • Stuck/blocked EGR valve / passages
  • Faulty camshaft position sensor
  • Defective compute
  • P1105MAP/BARO Pressure Switch Solenoid Valve
  • Check and clean the MAP sensor, or replace.
  • P1492EVAP Canister Purge Control/Solenoid Valve (Circuit)
  • Replacing the purge solenoid will clear code P1492 This should also clear code P0300 as well.

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 2000 broken wire


Here is a link to a Nissan forum that discusses your problem..In the 2nd post there is a link to the service manual for trouble shooting this issue. It seems that it is more common than not.

I have used obd11 and its give me 2 codes kwp2000 & iso9141 how do i find out wa they are


http://www.infobarrel.com/How_to_Read_OBD1_Automobile_Diagnostic_Codes

That site tells you how to do it. Basically you use a paper clip to jump 2 ports on the obd1 connector and the check engine light will flash a certin number of times and you write down how many times it flashes. Example. flash flash pause flash flash flash is a code 23.

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.
