What does the MAF sensor on a Ford Ranger do?

A MAF sensor measures the density of the air entering the intake manifold. It passes this information onto your Ranger’s ECU. The ECU uses this information along with other sensor data to control the amount of fuel that enters the combustion chamber. If you do determine that you need a new mass airflow sensor, they aren’t too expensive.

Is the Ford mass air flow ( MAF ) sensor inside?

Ford has used a Hot-Wire type mass air flow sensor for many years that either comes with or without an internal air temperature sensor. If the MAF sensor has 6 wires, then this is a dead giveaway that it has the air temp sensor integrated inside.

What does p0102 stand for in MAF sensor?

P0102: Mass Air Flow (MAF) Circuit Low Input. P0103: Mass Air Flow (MAF) Circuit High Input. MAF sensor malfunction that DOES NOT light up the check engine light (CEL).

How to change the antenna wire on a Trac?

Slide the stereo out of the opening and unplug the two (or three) plugs on the back, as well as the antenna wire. Use the 7mm socket to unscrew the two screws above the HVAC controls. Pull out on the stereo surround and the clips will pop out.

Which is MAF code light up the Check Engine light?

MAF Codes that light up the check engine light (CEL) on your instrument cluster. P0102 MAF Signal Low Input to PCM. P0103 MAF Signal High Input to PCM. P1100 MAF Circuit Intermittent Voltage Input. P1101 MAF Sensor Circuit Output Voltage low During KOEO Self Test. MAF sensor malfunction that DOES NOT light up the check engine light (CEL).

How does Control Trac transfer case modification brown wire?

By interrupting the power flow to the TCCC when in 4 low, the transfer case disengages the front driveshaft, even though the planetary reduction gears are engaged. This results in a true 2wd low range. The system used in the early second generation Explorers was very similar to the later second gens.

Is it important to test the mass air flow sensor?

It is crucial, yes very critical that you first check that there are no air leaks between these two. Air entering after the mass air flow sensor into the engine will negatively impact fuel injection. And will skew the results of your tests which could result in the replacement of a good MAF (and in the process throwing money away).

How many wires are in the Ford mass air flow sensor?

The Mass Air Flow Sensor on your FORD may have 6 or 4 wires coming out of the Plastic Round Air Filter Box. If the ford mass air flow sensor has 6 wires, this indicates that the Air Temperature Sensor is integrated within the mass air flow sensor itself.

Where is the air temp sensor on a Ford?

If the ford mass air flow sensor has 6 wires, this indicates that the Air Temperature Sensor is integrated within the mass air flow sensor itself. If it’s a 4 wire sensor, then the Air Temp Sensor is located externally, usually on the Air Duct connecting the Round Air Filter Assembly to the Throttle Body.

What happens when a catalytic converter is misfiring?

When a cylinder misfires, it can cause a cylinder’s worth of hot, unburnt to fuel enter the catalytic converter, melt the ceramic material inside. As the inside of the catalytic converter heats up it can start to break apart, plugging the exhaust, which causes problems to keep cascading. But catalytic converters aren’t the only concern.

Are there any problems with the Ford Escort?

However Ford has been unable to pull any codes, and wants an outrageous amount to check the car system by system. The car runs and drives fine, however occasionally on the highway the car will surge, as if the fuel supply were being momentarily cut off.

What’s the Abt on a Ford Escort engine?

When the eng is switched off it keeps running for abt 3 seconds before it stops, and the tach goes all the way to the high side of the gauge. When the eng is restarted the tach does not move until you rev the eng up to abt 2,000.

Why is the Check Engine light coming on on my Ford Escort?

The check engine light has been coming on for quite sometime. However Ford has been unable to pull any codes, and wants an outrageous amount to check the car system by system. The car runs and drives fine, however occasionally on the highway the car will surge, as if the fuel supply were being momentarily cut off.

What does MAF code on Check Engine light mean?

MAF Codes that light up the check engine light (CEL) on your instrument cluster. P0102: Mass Air Flow (MAF) Circuit Low Input. P0103: Mass Air Flow (MAF) Circuit High Input. MAF sensor malfunction that DOES NOT light up the check engine light (CEL). Lean and/or Rich code (s). Fuel Trim code (s). A tremendous lack of power upon acceleration.

What happens when the MAF sensor gets dirty?

MAF sensors have a tremendous tendency to get dirty and cause several headaches that may include: BAD gas mileage, higher emissions, and/or lack of power. For the most part, when one is dirty… the truck, or van or SUV seems to drive OK, but not with the same peppiness as before.
