yes, P2127 refers to throttle / pedal position sensor switch E circuit low input , and P2138 refers to throttle / pedal position sensor switch D & E voltage correlation . yours is a drive by wire technology vehicle ( no throttle cable) , you have an issue with that system / circuit .

Thanks for using Fix Ya !

SOURCE: obd1 scan tool will notaccess

A couple of ways to check and see if the computer is ok first:
check engine light must come onwith they in on position
The fuel pump must run for two (2) seconds with the key ON
There must be a 5 volt reference at sensors like map, TPS
Must communicate with scan tool
The ORANGE wires at the computer are you power input wires one has 12V all the time this is your KEEP ALIVE MEMORY
one is 12 with the Key on you MUAT HAVE VOLTAGE AT BOTH
Check the computers Ground most are out under the hood and are brown wires
Try the GM TAP TEST this is a factory authorized test with the computer connected and you verified all of the above SLAP the computer with the open hand firmly not too hard but firm see if anything changes,
Do not disconnect the battery you will erase all the codes!
Please contact me if you need any additional information.

Is there an OBD1 readear for a 95 Nissan Maxima?


In rare cases your 1995 Maxima might use OBD2 but it is probably a OBD1. You could try an OBD1 reader but unfortunately OBD1 was not anywhere as useful for diagnostics as the OBD2.

Where do I find the codes?


You plug a OBD2 scan tool to your vehicle and that will read any fault codes. You can take that fault code and look it up online, many scan tools will tell you what they are

Correct CAN/OBD2 Reader/Scanner


Hi Solomon, If you would like to buy a scanner you should be aware that using the device points you in the direction of a fault but is not an automatic fix for your vehicle. As an example, the diagnostic scanner may indicate a fault with the throttle position sensor. You go out, buy a replacement, fit it and after fitting the same fault shows up again, because the problem is with the adjustment not the unit. I like the Carman Scan. Regards John

ABS LIGHT IS ON , BRAKE AND OIL LIGHT FLASHES


ABS light on meansd your car has the obd2 code problem, you need a scan tool to test out the code, and i know this tool can help you diagnose the code and delete/reset it. Or you can take your car to the local dealer to check out it, then they will tell you how to fix it.

How do you reset the service engine light?


Locate the diagnostic connector. On the 1997 Nissan Maxima the connector is located in the OBD2 standardized location under the driver-side dash, slightly to the right of the steering column. With the ignition key in the "OFF" position, plug the connector of the scan tool into the diagnostic connector of the car. Turn the ignition key to the run position but do not start the engine unless instructed to by the scan tool.

Turn the scan tool on and select "Global OBD2" from the main menu. Select "Diagnostic Trouble Codes" from the first sub-menu, and then "Read Trouble Codes" from the second sub-menu. Write down all listed codes and their descriptions before erasing them. This will save time if you must perform additional diagnostics.

Press the back button on the scan tool until the second sub-menu is displayed, and select "Erase Codes" or "Clear Codes," depending on the manufacturer of the scan tool. A message will appear asking you to confirm your desire to erase the codes and other stored data. Select "Yes". The scan tool will alert you when the codes have been erased.

Test drive the vehicle to verify the repair is complete. The 1997 Nissan Maxima on-board computer will run a series of tests on the systems in the vehicle, including emission control devices. To complete these tests you must take two test drives that include a variety of driving conditions, with a 2-minute cool-down between each test drive. If the service engine soon light does not come back on during these two test drives, you have completed the repairs and the reset.

My check engine light is on even after replacing the gas cap. I have replaced the battery and tried most tricks .


What is the code? Most auto parts stores will read the code for free. My guess is this is a Faulty O2 Sensor causing the problem. The code that will appear when scanned will tell you.
