Did you replace the MAF mass airflow sensor ? If you did not, clean it with electronics cleaner so it won't damage the sensor. that could be the cause. also the EGR vavle would cause a problem like that.

Ok what do you call the sensor


Ok what do you call the sensor Arnold, List of sensors, could be more on different vehicles. You will have to have scanned to get codes to diagnose problem.
  • Crank Position (CKP)
  • Cam Position (CMP)
  • Engine Coolant temp (ECT)
  • Manifold Absolute Pressure or Mass Air Flow, MAP and/or MAF.
  • Throttle position (TPS)
  • Accelerator pedal position (APPS)
  • Heated Oxygen sensor in exhaust (H02S)
  • Wheel Speed Sensor
  • Tire Pressure sensor (TPMS)
  • Intake/Ambient Air Temp (IAT) "I hope this helped you out, if so let me know by pressing the helpful button. Check out some of my other posts if you need more tips and info."

My Nissan Almera keeps cutting out completely whilst driving?


run the fault codes and look for cam/crank position sensors.
faulty or loose connections may cause this fault. If you have more than 1 key in the ignition then it has been known that the mass of swinging keys will switch off the ignition
(current recall on all GMC ignition switches for just this reason)

Nissan Almera wont start with code P0345


Code 345 means the cam sensor on bank two is not sending the correct signal to the engine computer. So no spark.
If you have replaced the sensor, the problem could be the cam or the wiring from the sensor to the computer.

2003 Nissan Altima 2.5L Service Engine Soon Light is on, Auto Zone says codes are for MAF and O2 Sensors. Car hard to start after driving a while but when starts appears to run smooth. Auto Zone thi


ok lets start with the codes they say your getting. P??? which 1's and how many. there are few o2 sensors, are they next to the Exhaust next to the converter? MASS AIR FLOW -MAF use this, for now i am guessing, until i see the correct codes your are getting. this could be the 1 you may have below, please read it........
  • P0103
    Mass Air Flow Sensor Circuit High Input
  • Possible causes
  • Faulty mass air flow sensor
    - Intake air leaks
    - Dirty mass air flow sensor
    - Dirty mass air filter
    - Mass air flow sensor harness is open or shorted
    - Mass air flow sensor circuit poor electrical connection
  • Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.
  • possible symptoms Engine Light ON (or Service Engine Soon Warning Light)
    - Engine stall
    - Engine running rough
    - Excessive fuel consumption
    - Excessive smoke
  • the code is generated when An excessively high voltage from the sensor is sent to Engine Control Module (ECM).

My almera 1.6 2004 model coils not recieving power.


ok, i will try and help you as much as i can. first you should be getting 12 volts a pulse and a ground( negative ). if you're getting the 12 volts and the grounds but no pulse the the car has 2 sensors, one is the cam and the other is the crank. those sensors provide pulse to one for the injectors and the crank is for the coil packs. you can test for pulse by using a noid light or the normal test light. just connect the test light to 12 volts terminal and have someone crank over the engine. if you don't get a low flickering light then you neeed to change the sensor

I have a 2003 Jaguar S Type V6 and I wanna know how do you know if you need to replace the mass air flow sensor or whatever! I have changed the plugs and coils on it all ready cause it was starting rough...


Rather than take a stab in the dark replacing items - get the codes scanned and this should show what area the fault lies in. Normally if there is a fault with the MAF (mass air flow meter) it would normally show as a check engine light (MIL) - is this warning on? So many things can affect these engines from O2 sensors, coil misfires, bad cable connections etc etc. - so best move get the car scanned. Hope this helps (and saves money) good luck.

Re:nissan almera 2006 1.5 petrol.\r\ntruble


I am having the same problem. I have changed my cam shaft sensor and though it has improved a little but the problem is still there, i've been told it could be the 'air flow meter'. I am having somebody check it out tonight (plugged into some computer to ID the problem)

Car jerks on freeway and engine shuts off.


It sounds like your Mass Air Flow Sensor is faulty. These sensors will normal show fault when cruising at highway speeds causing the vehicle to almost stall or stall. Replace the Mass Air Flow Sensor with a known good one and test drive the vehicle. This will most likely repair your concern.

This is on the air/fuel sensor that is mounted in the exhaust manifold right behind the radiator. You will need to remove a heat sheild to see it but you should see the wires coming out of it. Also a spiecial socket is needed to get it out without damaging the wiring.
