SOURCE: 2001 Nissan Altima with service engine light on

I would check your intake gasket. Get your self ome carb cleaner in a spray form/can and perfrom this test. Run the car and spray the carb cleaner on your intake gasket which is right by your injectors. So pretty nuch spray it at the injector rail and listen fot change in idle, If the idle changes, the intake gasket is torn and you are running lean, because of a vaccum leak. Common problem on your model car. Perform test and let me know what you find.

SOURCE: Engine sound humming low and high

If the engine is overheating, that's why the light is on. Its a P0271 code I beleive. Its a "OVERHEATING" code.Dont drive the car. You are loosing coolant or its out of coolant, check the coolant level in the overflow bottle. We have seen some headgasket issues on that model car. I would remove the spark plugs and look into the cylinder for any signs of coolant on top of the pistons. Let me know what you find.

SOURCE: Fuel gauge slow to rise and service engine light on

the fuel level sending unit might be shot. mine went out and every time the gauge hit 1/4 tank the needle dropped. its a $80 part, simple to fix yourself if you are out of warranty otherwise they will try to nab i with a $280 bill that includes changing the fuel pump which is not required.

Most auto parts stores will scan the engine codes free or allow you to use theirs on site. Scan the code and post it back here for additional help.

SOURCE: My 97 nissan altima is occasionally stalling out

This happened to my 1997 Altima GXE a couple years ago. The coolant sensor is bad ($30-40 part). The coolant sensor is reading that the temp is cool on a warmed up engine and actually causes the engine to run rich (thinking it is a cold engine). The problem is intermittant and happened at the worse times.

I have a 2000 nissan frontier v6 that is spitting and sputtering when driving.
no VIN posted or country and means ,impossible to know this.:
he Nissan Frontier is a nameplate used on two different pickup truck models by Nissan: VG30 V6???
VG33 V6???
the Nissan here has a cam timing belt, if allowed to slip at 60 to 100kmiles the engine is wrecked, valves in the cyl. head bend!

so do you ignore this belt>? if yes it will get worse. $$$$$$$$$$$$
do not disconnect the map, and leave it like this, ever.
forget evap code until engine is fully serviced.
all Nissan's are interference engine,<< belt never IGNORE
1: check the cam belts for fray,cracked or skipped time.
2: new spark plugs (before o2, fuel cannot burn with bad spark.)
3: check fuel pressure to spec, FPR can be bad. and low pressure.
4: pulling map can kinda hid a bad FPR, if pressure is low.
5: new distributor timed wrong. as most noobs do,
6: clogged 1/2way injectors.

I have a 2002 Nissan Maxima. The car is an automatic and bogs down when I start to accelerate it also almost dies when I come to a stop.
so just and engine problem and 50 causes, actual,
when did car last run perfectly, never? (just bought it bad) or last decade? even bad fuel; of car was parked for over a year.

miles on engine is what 300k?miles.
sure filters, if not in the fuel tank. both air and fuel both
and new spark plugs, no engine told
gen 5 car. yes.
2 engines then

its 20 years old, ever do a full tune up, this decade?
scan the PCM yet for DTC errors? (p03xx errors/) oops
6 new spark plugs. oem spec, for sure.
and 6 new COP boots , the old ones are JUNK (pure)
seen here
https://www.rockauto.com/en/catalog/nissan,2002,maxima,3.5l+v6,1431961,ignition,spark+plug+/+ignition+coil+boot,10150

stalls cured now ?
even partially clogged injectors, try Chevron fuel injector cleaner? to tank,? it can work ,others not.

last 2 is EGR, if it sticks open engine wants to stal.
bad ldle (too low), is stuck IAC valve.
TECH, bad engine, bad spark or bad fueling 1,2,3 in order.
we can not burn fuel(gas) lacking good spark so fueling is last,

or melted CATs and huge engine power loss.
them block exhaust flow, but is an easy vacuum test. (a tool)
low compression, lower than 150PSI on any of the 6.

if all is good, above fuel pressure is checked for spec, PSI
if low the FPR bad or pump weak
the service manual covers all PUMP ,FPR and injector leakdown and balance tests. using hand gauge. at the rail.

How do you fix intermittent low idling on 2011 Nissan np300 ( petrol)
Sounds like you might have dirty fuel or water in the fuel (or a bad fuel filter). The first thing I would do is add a bottle of HEAT to the gas to take up any water. If that's the problem, change gas stations--stay with the major brands. If the problem persists, change the fuel filter.

Oil capacity of a 2.5 tdi nissan np300
During regular service of NP300 takes 4.3 liters of engine oil. Nissan NP300 really needs high quality motor oil. Lots of Nissan vehicles produced in 2009 had 2.5 motor under the hood. Having model code YD25DDTi this engine should be filled up with Synthetic 5w30 type of oil. Choosing normal Synthetic 5w30 oil for NP300 2.5 engine you ensure its long lasting work.

This is the same info for your 08 model. Please make sure to use 5w~30 full synthetic. Mobil 1 or Castrol.

My car is Nissan np300 2011 and is showing the code p1622 inj adj val unregistered this was after fitting new injectors what can that be
Sometimes (depending on the vehicle) the light will not go out by itself (after fixing the problem). If so, _must_ be reset (''cleared'') by a code reader tool. It is also possible you still have a different problem. Only the service book can tell you meaning of the codes. (Not a book you can buy at an auto parts store, but a dealer service manual for that specific vehicle).

My Nissan np300 2011 is showing code p1622 inj adj val unregistered what is the problem
First of all. Changing injectors about just because the power of your vehicle is low, is highly unlikely to solve your problem. Like trying for a grand slam when blindfolded.

Second of all it is highly probable that unless your new injectors were purchased from the dealer for your car specifically, that you got similar injectors of a different impedance, or perhaps entirely different injectors, this would easily explain your CEL code because the engine computer has no idea what to do with the injectors you installed.

My advice would be to go back to the original injectors, and try to solve your low power issue another way like checking the O2 sensor, or making sure you TPS is properly adjusted.

Code p0734 I just replaced eng. and trans. now have this code.
Engine Light ON (or Service Engine Soon Warning Light)
- Incorrect transmission shifting Possible causes - Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit Tech notes Start by inspecting the transmission fluid level and condition, and change fluid if necessary. When is the code detected? P0734 is detected when A/T cannot be shifted to the 4th gear position even if electrical circuit is good. P0734 NISSAN Description This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by Transmission Control Module (TCM) as follows:

Torque converter slip ratio = A x C/B

A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from Engine Control Module (ECM)
C: Gear ratio determined as gear position which TCM supposes

If the actual gear position is higher than the position (4th) supposed by TCM, the slip ratio will be more than normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.
