Mass Air Flow Sensor

The first step to replace Mass Air Flow Sensor (MAF)/intake air temperature (IAT) sensor is to toggle the ignition off while removing the maf electrical connector. The air cleaner intake duct must be taken off first before removing fasteners from the maf sensor. Extract the maf sensor unit while removing its accompanying seal then eliminate the used seal. The new maf sensor needs to be installed by placing the maf sensor seal and maf sensor into position and fastening it with maf sensor screws that should be tightened to 4 n.m (35 lb in) according to service precautions advice. The maf sensor installation requires returning the air cleaner intake duct to its position after reconnecting the maf electrical connector.

To replace the mass air flow/intake air temperature (MAF/IAT) sensor, disconnect first the maf/iat sensor electrical connector and remove clamps securing the maf/iat sensor assembly to the air cleaner and intake air duct. With care, remove the maf/iat sensor from the air cleaner and intake air duct. Carefully reposition the maf/iat sensor back into the air cleaner and the intake air duct, and install the clamps to hold the structure and secure the assembly of the maf/iat sensor, tightening the clamps to 3 n.m ( 27 lb in). Ultimately, reconnect the maf/iat sensor electrical connector .

Starting the Mass Air Flow Sensor/iat sensor replacement requires users to disconnect power to the wiring while removing the clamps surrounding the Mass Air Flow Sensor/iat sensor assembly between the air cleaner and intake air duct. Handle the Mass Air Flow Sensor/iat sensor with extreme care when removing it from the air cleaner and intake air duct because any damage should be avoided along with drops and never touch sensor elements or let solvents and lubricants come near them. A limited quantity of soap solution should be applied specifically to help with Mass Air Flow Sensor/iat sensor assembly placement. The technician should install the Mass Air Flow Sensor/iat sensor by placing it in the air cleaner and intake air duct while maintaining careful handling. The Mass Air Flow Sensor/iat sensor assembly needs clamps for attachment to the air cleaner and intake air duct while tightening them to 3 n.m (27 lb in) followed by connector reconnection.

Start the mass air flow (MAF) and intake air temperature (IAT) sensor replacement by disconnecting the maf/iat sensor electrical connector and removing clamps securing the maf/iat sensor assembly to the air cleaner and intake air duct. Perform this step cautiously to prevent damage to maf sensor and air inlet screen and avoid sensor element contact. Also protect the sensing elements from contamination by solvents or lubricants. Use a small amount of soap-based solution for installation purposes. A low amount of soap solution functions as an installation aid during the work. The installment process requires you to extract the maf/iat sensor both from the air cleaner and intake air duct with extreme caution. Follow these steps to install the maf/iat sensor : first place it in the air cleaner and intake air duct and secure it using clamps which must be tightened to 3 nm (27 lb in) torque. After that complete the installation by reconnecting the maf/iat sensor electrical connector .

You should handle the Mass Air Flow Sensor/intake air temperature (MAF/IAT) sensor with care while replacing it to protect the honeycell at the air inlet end and preserve the sensing elements from any contact with cleaning solvents or lubricants. A small amount of non-silicone lubricant will help with air duct installation. The air cleaner outlet duct must be removed first before extracting the gray connector position assurance (CPA) retainer and disconnecting the Mass Air Flow Sensor/iat sensor electrical connector through pushing down on the black clip. The technician should remove the air cleaner sensor by carefully loosening the Mass Air Flow Sensor/iat clamp before taking the item from the air cleaner housing. Before installing the Mass Air Flow Sensor/iat sensor into the air cleaner assembly guide the embossed arrow towards the engine direction and then secure the Mass Air Flow Sensor/iat clamp at 7 n.m (62 lb in). Connect the Mass Air Flow Sensor/iat sensor electrical connector afterwards reuse the gray cpa retainer followed by reinstallation of the air cleaner outlet duct.

The first step for replacing the Mass Air Flow Sensor/intake air temperature (MAF/IAT) sensor involves handling the sensor gently to preserve the air inlet honeycell structure while staying away from sensor elements and refraining from exposing them to cleaning materials or lubricants. You should apply a small amount of non-silicone based lubricant to the air duct for assembly purposes. Start by taking off the air intake resonator followed by disconnecting the Mass Air Flow Sensor/iat sensor electrical connector. Start by loosing the clamp which holds the Mass Air Flow Sensor/iat sensor to the air cleaner housing before removing it from the assembly. When installing the Mass Air Flow Sensor/iat sensor keep its embossed arrow facing the engine direction followed by attachment to the air cleaner housing with clamp tightening. The Mass Air Flow Sensor/iat sensor electrical connector should be connected after which the device's air intake resonator can be installed.

Replace the Mass Air Flow Sensor/intake air temperature (MAF/IAT) sensor while avoiding damage to the air inlet honeycell and maintaining contact with cleaning solvents or lubricants; a light application of non-silicone based lubricant on the air duct will facilitate installation. Start by taking off the air cleaner outlet duct followed by removing the gray connector position assurance (CPA) retainer to disconnect the Mass Air Flow Sensor/iat sensor electrical connector through black clip depression. Lease the Mass Air Flow Sensor/iat clamp before removing the sensor from its position on the air cleaner assembly. Install the new Mass Air Flow Sensor/iat sensor by directing its embossed arrow towards the motor and fasten it to the air cleaner assembly until the clamp achieves 7 n.m (62 lb in). Continue by attaching electric wires to the Mass Air Flow Sensor/iat sensor before forcing in the gray cpa retainer while reinstalling the air cleaner outlet duct.

Start the replacement of the Mass Air Flow Sensor (MAF)/intake air temperature (IAT) sensor by removing the air intake resonator then disconnecting the maf/iat sensor electrical connection. You can replace the maf/iat sensor by first freeing its clamp from the air cleaner housing then removing the sensor from the assembly with protection for the air inlet's honeycell and sensing element areas. The correct installation of the new maf/iat sensor requires the embossed arrow to face the engine direction. Position the sensor on the air cleaner housing then fasten the clamp before plugging the electrical connector and reinserting the air intake resonator. The installation of the sensor requires a tiny amount of non-silicone based lubricant on the air duct as well as gentle handling of the sensor during the entire process.

The replacement process starts by disconnecting the Mass Air Flow Sensor (MAF)/intake air temperature (IAT) sensor electrical connector then unfastening the clamp on the air cleaner outlet duct that surrounds the maf/iat sensor before handling the air cleaner outlet duct for removal. Treat the maf/iat sensor with extreme care because damage to the screen at the air inlet end can occur; avoid all contact with the sensing elements by using spo p/n 12345884 lubricant or its soap-based equivalent to help with the installation. The following step requires users to unfasten the clamp at the maf/iat sensor position on the air cleaner box then take out this maf/iat sensor. The maf/iat sensor installation requires direction of the arrow toward the air cleaner box during sensor placement followed by maf/iat sensor clamp tightening at the air cleaner box to 4 n.m (35 lb in). After reconnecting the air cleaner outlet duct to maf/iat sensor you must fasten the clamp to 4 n.m (35 lb in) before securing the maf/iat sensor electrical connector.

To remove the mass air flow (MAF) and intake air temperature (IAT) sensor, treat the sensor with care so that it does not damage the honeycell at the air inlet end and do not touch the sensing elements nor allow any cleaning solvents or lubricants to touch them; a small portion of a non- silicon-based lubricant can be applied on the air duct to help you out during installation.
