what do you think of nisssan altima 2.5s

Charlieluvboy:
Pls my Nissan Altima 2002 model (Auto) refuses to start once it starts it doesn't last more than 3secs before its switches off back. Someone said the air flow meter needs replacing how true is this.

Daniboygeorge22:
Please who can tell me about reliability and common problems of a nissan altima SV 2010. ? I am thinking of gettjng one. Though second hand value is poor in Nigeria..

Hello Guys,

Does anyone know a reliable person/place I can get the steering wheel oil for Infiniti QX56 2005.

Thanks all.

IghKes:
Anybody here? Please I need advice.my Infiniti g35x 2008 is having steering rack leak.its severe I have to top up fluid any time am driving.
Can it be fixed.or can only be replaced

Smartchoiice:

In what sense? Your question is incomplete.

aieromon:


I assume you're referring to power steering oil. You can get PSF or any Dexron III ATF in ShopRite or Total filling stations.

You can also checkout https://myparts.com.ng/ if you're based in Lagos.

Hello bosses,

My 2011 Nissan Altima throws the following codes:

P0443
P0138
P0037
P2138
P0420
The car runs and drives great, btw

Costee:

Delete and re-scan after a couple of drive cycles.

P0138
P0037
P2138
P0420

I did some research online, and I found out that some of the codes are complimentary. But I feel, getting your experienced suggestions will be great before taking it to the mechanic.
The car runs and drives great, btw

Thanks you.

P0443 how i would diagnose it.

Diagnose the existing part.

First i would use a multimeter to confirm continuity, next i would use a 12v battery to confirm actuation, finally i would blow test with my mouth to confirm the valve is open when voltage is applied and closed when there is no voltage.

Diagnosis of the system.

I would use a scanner to actuate the evap purge solenoid to test for same functions as when it was connected to a battery.
The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the ECM.


P0138 : I would connect my scanner to the car and examine the live readings.
P0138 is a common OBDII code, the code is triggered when the voltage at the sensor remains above threshold for 20 seconds or more or when voltage to the sensor is to high.


You are looking at a possible faulty oxygen sensor bank 1 sensor 2 (hope you replaced the right one) downstream.

You are looking at a possible wiring issue.

You are looking at a possible faulty engine ECU.

P0037:
The code means that there is a problem with the heater element circuit of the heated oxygen sensor.

How i would diagnose. I would start by using a multimeter to check for resistance around the heater connectors when the sensor is disconnected, usually between 2-5ohms, as the word "heater" it is a heating element within the O2 sensor and would require a great deal of current to operate.

I would check the connectors for corrosion, I would check for any burnt fuses and replace.

Very importantly i would check that the wiring of the connector from the harness to the O2 sensor was in the right order, in the past I have seen connectors that pulled out and were installed wrongly on both the harness side and the O2 sensor side. For this you would need to download pics of the part and examine.

Next phase testing for voltage to the heater element from the engine ECU.

On the heater line from the engine ECU, install a multimeter, set to test for D.C voltage, start the car, there should be a short burst of 12v for about 3-5 seconds as a series of short pulses, with that you are sure the engine ECU is still providing voltage to the heater element.


P2138:

These sensors are a kind of potentiometers which transform the accelerator pedal position into output voltage, and emit the voltage signal to the ECM.

When defective they fall out of range BUT not because the device is defective, but because the resistance readings are out of range when at rest position.

Place scanner on live readings and check for the opening and closing angles when depressed fully and when at rest.

Refer to this thread and check your pedal again. https://www.nairaland.com/4880683/mature-cockroach-120km-hr


P0420: You have no catalyst, it's really not an issue, just install a spacer on the downstream O2 sensor.


Hope this helps.

P0138, P0037, and P0420 are some of the more common nuisances you find on most cars hereabouts, and which your mechs and techs would easily find answers to. If you really had an issue with P2138 your car would have been undrivable. Its presence is, therefore, a response that you don't have an ideal condition. This seems related to P0443. But even this might be innocent. So my advice, for now, is to check the pressure sensor on the evap canister, especially if water is present in its connectors. Changing this sensor could resolve the two codes. I want to believe that all your wiring connections are still intact.

Ibhope youbdid not waste your money on any stop leak. Replace the steering rack before it ruins your pump!

Please I need help,my Nissan primera 2008 salloon is consuming fuel excessively,my mechanic has cleaned the injector and the plugs still no difference . Please what do I do next. Please help cause it's alarming

Costee:

What's your rpm at idle? Is the CEL on?
Btw, no 2008 Primera.

judemurphy:
there is, you can Google it. But that's not the challenge. The issue is fuel consumption. How do I check the rpm
