What causes a Nissan Altima to have a p0102?
Here are the most common causes of P0102 in the Nissan Altima. They are presented loosely in order from most to least likely: MAF Sensor Dirty – Over the course of its life, the MAF sensor will often get so covered in grime that it’ll no longer get an accurate reading.
What does code p0102 mean on the ECM?
Mass or Circuit Airflow (MAF) Circuit Low Voltage Input What Does P0102 Mean? The Mass Airflow (MAF) sensor measures the amount of air entering the engine. When code P0102 is set, there is a low voltage output to the ECM, PCM, or ECU depending on your car type (check your owner’s manual for your specific car).
What does the code p0102 mean on a Honda Accord?
All our repairs are backed by our 12-month / 12,000-mile warranty. The code P0102 code is often associated with P0100, P0101, P0103 or P0104 trouble codes as they are closely related. P0102 is the general code for a problem with the Mass Airflow (MAF) Sensor having a low voltage output to the Engine Control Unit (ECU).
What does mass airflow sensor p0102 do?
Since P0102 has to do with the Mass Airflow Sensor, which is a huge part of the Altima’s engine combustion process metering, it is going to cause noticeable symptoms. Usually, one or more of these symptoms will occur, but it’s not uncommon to have no symptoms other than the check engine light.
Here are the most common causes of P0102 in the Nissan Altima. They are presented loosely in order from most to least likely: MAF Sensor Dirty – Over the course of its life, the MAF sensor will often get so covered in grime that it’ll no longer get an accurate reading.
How much does it cost to diagnose a p0102 code?
The cost of diagnosing the P0102 code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
What does p0102 mean on the MAF sensor?
The Mass Airflow (MAF) sensor measures the amount of air entering the engine. When code P0102 is set, there is a low voltage output to the ECM, PCM, or ECU depending on your car type (check your owner’s manual for your specific car). P0102 Symptoms
What are the symptoms of a p0102 engine problem?
P0102 Possible Symptoms 1 Engine Light ON (or Service Engine Soon Warning Light) 2 Engine stall 3 Engine running rough 4 Excessive fuel consumption 5 Excessive smoke
What are the symptoms of a bad mass air flow sensor?
7 Symptoms of A Bad or Failing Mass Air Flow Sensor 1. Check Engine Light (CEL) 2. Difficulty during engine start 3. Poor fuel economy 4. Rough Engine Idle 5. Engine hesitation during acceleration 6. Engine hesitation under load 7. Gas smell from exhaust pipe
How to replace a mass airflow sensor in a car?
In most vehicle models, all you have to do is: 1 Disconnect the part of the air intake duct that connects to the MAF sensor. 2 Carefully unplug the sensor electrical connector. 3 Unscrew two or more sensor mounting bolts. 4 Remove the old sensor. 5 Install the new one.
Can a bad MAF sensor cause a bad transmission?
You may have a bad MAF sensor if you notice one or more of the following symptoms: On some vehicle models, the MAF sensor also informs the computer about air intake temperature and engine load (to control some automatic transmission functions). So a bad MAF sensor on these cars can cause an even wider range of symptoms.
What is the diagnostic code for mass airflow?
P0101 is a diagnostic trouble code (DTC) for “Mass Airflow (MAF) Circuit Operating Range or Performance Problem”.
What causes the mass air flow sensor to malfunction?
Potential causes for this trouble code may include: Dirty or contaminated mass air flow sensor. Failed MAF sensor. Intake air leaks. MAF sensor electrical harness or wiring problem (open, shorted, frayed, poor connection, etc.)
What causes a fault reading on a MAF sensor?
The wiring or MAF sensor may be too close to higher voltage consuming components. This includes alternators, ignition wires, etc. which can cause interference in the output signal to the ECU. A vacuum leak can also cause a fault reading and can lead to other problems that may indicate several codes at the same time.
What causes MAF sensor to have trouble code p0101?
Potential causes for this trouble code may include: MAF sensor electrical harness or wiring problem (open, shorted, frayed, poor connection, etc.) Note that other codes may be present if you have a P0101.
What is the p0113 code for an air temperature sensor?
P0113 Code: Intake Air Temperature Sensor 1 Circuit High Input – In The Garage with CarParts.com IAT or Intake Air Temperature Sensor Testing
How much does it cost to diagnose Nissan code p0113?
The cost of diagnosing the P0113 NISSAN code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour. When is the P0113 NISSAN code detected? – An excessively high voltage from the sensor is sent to ECM.
What does the Check Engine Light code p0102 mean?
Code P0102 does not pose any serious danger to the driver or the vehicle and there are no drivability issues that may occur. However as the case with all Check Engine Light codes, it should be fixed as soon as possible to prevent any further damage to your vehicle.
What’s the problem with my Altima MAF sensor?
P0101 – MAF Sensor Problem.. Hi. Everyone. MIL lamp for my 2013 altima 2.5S illuminated. I checked the error code using OBD2, and the code was P0101. I bought MAF sensor cleaner and a new air filter (the old air filter was very dirty). After cleaning the MAF sensor, I replaced a new air filer.
Can a bad manifold pressure sensor cause p0101?
I did some research about P0101, and bad manifold absolute pressure (MAP) sensor will cause P0101. How can I read the value of MAP sensor data using torque app. When I displayed “intake manifold pressure”, the torque app always shows zero values.
Since P0102 has to do with the Mass Airflow Sensor, which is a huge part of the Altima’s engine combustion process metering, it is going to cause noticeable symptoms. Usually, one or more of these symptoms will occur, but it’s not uncommon to have no symptoms other than the check engine light.
