Fault reading fuel injection feedback on terrano 2

fuel filter, computer

This is the closest I've come to the code you are looking for. I searched all Dodge codes and didn't see any with a "point 2" but I found code P0172. According to EngineCodes.com your fuel mixture is probably too rich. This is what the site had to say:

Possible Causes for this Code:
- Faulty front heated oxygen sensor
- Ignition misfiring
- Faulty fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure
- Faulty Mass Air Flow (MAF) sensor

This code is detected when:
- Fuel injection system does not operate properly.
- The amount of mixture ratio compensation is too large. (The mixture ratio is too rich.)

Possible symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Excessive Fuel Consumption

P0172 Dodge Code Description:

With the Air/Fuel Mixture Ratio Self-Learning Control, the actual mixture ratio can be brought closely to the theoretical mixture ratio based on the mixture ratio feedback signal from the heated oxygen sensors 1. The Engine Control Module (ECM) calculates the necessary compensation to correct the offset between the actual and the theoretical ratios.
In case the amount of the compensation value is extremely large (The actual mixture ratio is too lean.), the ECM judges the condition as the fuel injection system malfunction and light up the MIL (2 trip detection logic).

Hope this helps!

Probably you might face a problem on the injection pump with the Advance or retar positioning,and I believe that is controlled by the vehicle ECU. The Diesel Knocking you receive should be this fault.

Pick-up after the inspection results are as follows: 1. Engine starts without high-pressure fire; 2 engine nozzle on the fuel injection pulse measuring less; 3 Turn the ignition switch, the engine warning light does not shine (under normal circumstances, turn the ignition switch, engine fault light should be lit. electronic control unit after starting the engine electronic control components for 4 ~ 6s self, confirmed there is a fault fault lights lit, no fault fault light goes out). Taking into account the car ignition and fuel injection are directly controlled by the ecu, ecu lack of work is likely to be unable to work due to voltage.
or you can ask the 24 hrs live obd vas5054a technical support, they will like to help you, good luck

on nissan terrano diesel: had a fault cose 77 and a white smoke, no power. i changed the fuel filter and cleaned the fuel line from the tank to the fuel filter. it solve the problem.

When was last "healthy" tune up? Plugs, wires, all fluids & filters - especially fuel filter??? I'd start there and run a good fuel system cleaner through it and avoid cheap gas.

DTC P0171 is set when fuel trim is driven rich beyond a certain value. Possible causes are:
1. Exhaust system leak.
2. Improper fuel pressure.
3. Fuel injector restricted.
4. Defective heated oxygen sensor No. 1.
5. Defective Manifold Absolute Pressure (MAP) sensor.
6. Defective Engine Coolant Temperature (ECT) sensor.
When the air fuel ratio feedback is stable after the engine is at operating temperature and the fuel trim has reached its limit of correction to the rich side. (2 trip logic).
Feedback from the HO 2 sensor influences short-term fuel trim and short-term fuel trim influences long trim fuel trim. Short-term values are temporary and not stored when the ignition key is turned off. Long-term values are stored in memory because they are part of the basic injection duration. Long term values affect injection duration in closed and open loop because they are used to calculate basic injection duration. It is important to remember that the actual fuel trim will be the opposite of the DTC. A system too lean, DTC P0171 will mean the ECM is making a + or rich correction.
read (and let me know)above data and Freeze Frame by using (example, generic) Scan Tool on # mode 2, etc.
Slowly accelerate the engine in the increments shown and record voltage,
grams/sec of MAF and SFT, LFT, Injection Pulse, Fuel Pressure, etc.
HTH,
Vehicle have MAF Sensor?

The cheapest way to go is to change the fuel filters first and the air filter. Then I would change the crankshaft sensor.

You may have to bit the bullet , and have the fuel pump changed before the fuel injection pump. The fuel pump in the tank can be loosing pressure to the fuel injectoin pump.
I think the lesser cost is the fuel tank pump vs. the fuel injection pump.

The system runs of fuel and air. No spark like on a gas engine.

So the problem can only be lack of fuel or lack of air getting into the vehicle air induction. A restriction in fuel or air will make the engine run poorly.

some black smoke comes out when i put foot down and loses power when goiong uphill i have a nissan mistral/terrano 2.7td
