Question about 2000 Nissan Maxima

1 Answer

P0505 Code HI, I recently notice my Servine engine light came on. I took it to my Mechanic who had a Diagnostic Test done and came up with the code P0505. He had it cleaned and told me it would be ok. After about 5 days the light came back on. I went back to him, had another Test done and told me i should see a Nissan dealer. Said it is ok to drive . 4 days later the light went off.However today has i was about to drive out i noticed the steering vibratin and all the light came on( Slip, Tcs ,Abs and the servive Engine light as well) I then shut the engine off and started again; it wont stay on unless i have my leg on the gas pedal; when i take my leg off it shuts down

First make sure that your wires to you iac(idle air control) motor are ok. Also that the pins in the connectors are not damaged. Most likeley you need to replace the iac motor and follow a relearn procedure for the pcm.(powertrain control module)
The iac is most likely stuck in the extented position causing it to starve for air. You have to hold your foot on the gas to keep the throttle plate open enough to let air by for the engine to run.

What else, Check Engine Light, P0505, p0135, p0155, p1494 codes?


You can not work on a vehicle as your doing

Your checking for generic codes only & throwing
parts at it

You get a couple possible worn or failed parts & have
a few less codes

There is no need to clear ALL Data every time you change a part

You need to STOP

You need professional scan tool software to look at ALL data & go for a road test first

You keep clearing stored data ,so now the process will take longer

You work one code & one system at a time

NO PARTS get replaced that are not tested & found to fail
a test,thus a worn out part.

You need both Factory Emission & Diagnostic Manual, as well
as Wiring Diagram Book-- BEFORE-- you can even walk to the vehicle (Helm.Com)

You have nothing to go by,no system knowledge & no trouble charts,& no wiring diagrams to start your testing

If you got no scan tool & no volt meter & no oscilloscope,
your done,vehicles have to be tested to find a problem,any
problem,resolve it & continue on.

Check Engine Light On - Occasionally Stalls when shift to reverse.


If the check engine light is on, there has to be a code stored in the engine computer or body computer.
You may need to try another parts store, or a shop that has a scanner instead of a simple code reader.

Hi, The gas gauge is not working. Local mechanic tells me the module for the gas gauge needs to be replaced. Will not replacing the gas gauge module, keep the 'service...


Hello, the gas gage problem is caused by a defective gas gage sending unit, the sending unit is only sold as the entire Assembly which is called the fuel pump module, that said the gas gage problem is not related to the check/service engine light issue, that is an indication of a problem in the electronic engine control system or emission control system, when this light is on a fault code is put into the memory of the computer called the PCM, to retrieve this code requires a test be run called the OBD2 fault code test, this is done through the diagnostic connector that is in front of the steering wheel and under the dash, a code reader is needed, you can also get the code read for free by most discount auto parts stores like Kragen or Autozone.

Temperature gauge not working


Yep!... take it back to the mechanic and tell him/her to recheck the system (there's no such DTC (Diagnostic Trouble Code) as "bad electrical connection"... somebody's pulling your leg!
Whenever the 'CHECK ENGINE' (Service Engine Soon) light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on.
You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any code(s) which may have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE the problem and perhaps eventually fix the problem.

Check Engine Light won't go off


If you have an Advance Auto Parts store where ever you are, they will read the code and tell you exactly what to code is and what it means. Any mechanic who "guesses" isn't a mechanic at all - he's a thief. Emissions leak can be any number of things, but not the gas cap!
