FUNCIONAMIENTO DEL MAF EN UN SUZUKI SIDEKICK

SUZUKI Sidekick Mass Air Flow Sensor

Description: The Air Flow Sensor or Mass Airflow Sensor (MAF) is one of the components of an electronic fuel injection system and is found in many of modern vehicles. Most mass air flow sensors are one piece hermetically sealed units with no moving components.

Purpose: The Mass Air Flow sensor is used to measure (actually weight) the amount of air entering the engine. This measurement is used by the engine computer or ECM to calculate proper amount of fuel injected into the cylinders in order to provide optimum combustion and low emissions.

Maintenance Tips/Suggestions: SUZUKI Sidekick Mass air flow sensor requires no regular maintenance. On mass air flow sensors with a sense wire, this wire can become contaminated with dust particles. These particles can be removed with automotive solvents that are safe for the use on mass air flow sensors. SUZUKI Sidekick mass air flow sensors are commonly misdiagnosed. Before replacing the mass air flow sensor check for air leaks in the connecting air ducts and intake manifold. These leaks can cause similar symptoms as a malfunctioning mass air flow sensor.

Failure symptoms: Problems with Mass Air Flow sensors are common. Bad or contaminated SUZUKI Sidekick Mass Air Flow sensor can possibly cause a wide range of various vehicle drivability problems such as stalling, especially when the engine is cold, misfiring, poor acceleration, etc. In addition, a problem with the Mass Air Flow sensor often causes the "check engine" or "service engine soon" light in the vehicle instrument panel to illuminate.

AKA: MAF, Air Flow Meter

Location: The SUZUKI Sidekick Mass Air Flow sensor is usually installed in the intake air duct between the air filter and the throttle body mounted on the intake manifold. Some mass air flow sensors are mounted directly to the throttle body.

FUNCIONAMIENTO DEL SENSOR DE OXIGENO EN UN SUZUKI SIDEKICK

SUZUKI Sidekick Oxygen Sensor

Description: An oxygen sensor converts the status of the engine's exhaust gas oxygen content into a corresponding voltage signal. The oxygen sensor is sometimes referred to as a Lambda sensor on some European cars. Changes in the amount of exhaust gas oxygen result in a voltage change that is monitored by the vehicle's powertrain control module. Many oxygen sensors also have built-in heaters, to warm them to operating temperature more quickly. Prior to 1996, most vehicles had one oxygen sensor. After 1996 vehicle are equipped with two to four oxygen sensors.

Purpose: The SUZUKI Sidekick oxygen sensor supplies real time information about the engine's exhaust gas oxygen content to the powertrain control module. This information is used primarily to help calculate fuel delivery to the engine, which changes continuously while it is running. If the engine is running lean, the powertrain control module will sense this from the oxygen sensor's signal and increase the fuel supplied to the engine. Conversely, just the opposite occurs when the engine begins to run rich. On OBDII-(1996 and later) equipped vehicles, the sensors are also used to help determine the efficiency of the catalytic converter. The powertrain control module does this by comparing the signal of the sensor located at the inlet of the catalytic converter with the signal of the sensor located at the outlet of the converter.

Maintenance Tips/Suggestions: SUZUKI Sidekick oxygen sensors have a limited service period, replace as recommended in the owner's manual or when other conditions dictate, such as failing an emissions test or an oxygen sensor related diagnostic code from the powertrain control module indicating a faulty oxygen sensor. Some pre 1996 vehicles have an oxygen sensor light that appears when oxygen sensor replacement is needed.

Failure symptoms: Some symptoms of a faulty SUZUKI Sidekick oxygen sensor include poor gas mileage, a failed emissions test, "rotten-eggs" smell from the exhaust, poor engine performance. A faulty oxygen sensor will cause the Service Engine Soon or Check Engine light to appear, it's best to have the cause checked out immediately by a professional technician.

WARNING: Neglecting these warning signs can cause expensive damage to the catalytic converter, requiring replacement.

AKA: O2 sensor, Lambda sensor, HEGO sensor, front (upstream) oxygen, rear (downstream) oxygen sensor

Location: On pre 1996 SUZUKI Sidekick vehicles the oxygen is located in the exhaust manifold or front exhaust pipe near the exhaust manifold. Four cylinder has one oxygen sensor and V6 and V8 may has two, one for each engine bank. On 1996 “MAKE MODEL” and later OBDII equipped vehicles will have a least two oxygen sensors. An upstream or front oxygen sensor located in the exhaust system before the catalytic converter and a down stream or rear oxygen sensor located in the exhaust pipe after the catalytic converter. Some V6 and V8 equipped vehicles may have additional upstream and down stream oxygen sensors.
