The P0102 code is set when the Powertrain Control Module (PCM) detects that the mass air flow (MAF) sensor frequency signal isn’t performing in the normal expected range set by the manufacturer. This trouble code indicates that there’s a low condition within the mass air flow sensor or circuit. This diagnostic trouble code (DTC) is considered gener...
There’s a chance that you won’t see any unusual symptoms with the P0102 trouble code other than a Check Engine Light. However, there could also be some performance issues. Here are the most common P0102 symptoms. 1. Check Engine Light 2. Rough idle 3. Engine misfires 4. Black exhaust smoke 5. Hard start 6. Engine stalling 7. Reduced fuel economy
It’s quite possible that the mass air flow sensor is either contaminated or faulty. However, it’s not the only potential problem you are facing. Here are some of the most common P0102 causes. 1. Dirty or faulty mass air flow sensor 2. Intake air leaks 3. MAF sensor wiring problem 4. Dirty air filter 5. Faulty PCM (unusual)
Low – It’s unlikely that the P0102 code is going to stop you from driving your vehicle. At worst, you may notice some performance issues or have trouble starting the car. Most of the time, the faulty MAF sensor just leads to increased fuel consumption. Still, you will want to fix the problem. Not only is it important to keep the system running as i...
Once you perform a complete diagnosis of the system, you should determine what needs to be fixed. Here are some possible fixes that could resolve the P0102 DTC. 1. Clean mass air flow sensor 2. Replace the mass air flow sensor 3. Repair/replace faulty electrical connections 4. Repair intake air leaks 5. Replace air filter 6. Update/replace PCM
The most common mistake is to replace the MAF sensor without first cleaning it and checking the wiring. There are times when a new MAF sensor isn’t needed, so you will only be wasting your money. Specialized cleaners are made for the MAF sensor because it does become dirty and contaminated over time. Considering the price difference, it’s always be...
Even if you aren’t a professional mechanic, you should be able to figure out what’s causing trouble with the P0102 code. Here are a few simple steps to consider. 1. Check for other trouble codes. Use your compatible scanner and our trouble code listto determine if there are other issues that could be related. 2. Inspect the engine air filter. Repla...
After your diagnosis is complete, you should know what needs to be repaired. Here are some approximate costs for the repairs, assuming that you need to pay for both parts and labor. 1. Clean mass air flow sensor – $35 to $150 2. Replace mass air flow sensor – $250 to $400 3. Repair/replace faulty electrical connections – $50 to $500 4. Repair intak...
During your diagnosis, you may see other MAF circuit trouble codes. The most common codes associated with the P0102 DTC include the following: 1. P0100 – Mass Airflow (MAF) Circuit Problem 2. P0101 – Mass Airflow (MAF) Circuit Operating Range or Performance Problem 3. P0103 – Mass or Volume Air Flow “A” Circuit High 4. P0104 – Mass Air Flow (MAF) C...
The P0102 code is related to the mass air flow sensor and in most cases, it means that there’s a problem with the MAF sensor itself. However, there are other potential problems, such as a dirty air filter or a poor electrical connection, which is why a professional diagnosis is needed before replacing any parts. Whatever is causing the issue, you p...
P0102MA Product details. DESCRIPTION. Thanks to highly sensitive triggering levels, the P01 SCR series is suitable for all applications where available gate current is limited, such as ground fault circuit interruptors, pilot circuits in solid state relays, stand-by mode power supplies, smoke and alarm detectors.

Feb 9, 2022 · The P0102 error code usually indicates the mass air-flow (MAF) sensor is not receiving enough air from the engine. This can happen for multiple reasons that include bad connections from previously required wiring, corrosion in electrical connectors, and improper installations of aftermarket components.
This P0102 diagnostic trouble code (DTC) means that there is a low condition detected in the Mass Air Flow (MAF) sensor or circuit. The PCM detects that the actual MAF sensor frequency signal is not performing within the normal expected range of the calculated MAF value.
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 causes the P0102 code? The MAF Sensor has low voltage output problems which may have several causes.
Apr 5, 2022 · P0102 definition: Mass or Circuit Airflow (MAF) Circuit Low Voltage Input. Issue Severity: LOW – Continued driving for a short period of time is okay. Repair Urgency: Get this code fixed within the next month. Diagnosis: It is important to complete the entire diagnostic process when diagnosing the P0102 code.
