Symptom related diagnostic procedure(Using this section Introduction)

Most of the fuel and emission control system is electrically controllde, often making it difficult to diagnose problems in the
system, especially intermittent problems.
Before undertaking actual checks, take a few minutes to talk with a customer who approaches with a driveablity
complaint. The customer is often a good source of information on such problems, especially intermittent ones. Through
talks with the customer, one can find out what the symptoms are and under what conditions they occur.

General description

The Engine Control Module (ECM) operates the fuel system. If regulates ignition timing, air fuel ration, emission control
devices, charging system, idle speed control, air conditioning clutch engagement, etc. The ECM has the ability to adapt to
changing operating conditions.
The ECM receives input signals from various switches and sensors. Based on these inputs, the ECM regulates various
engine and vehicle operations through different system components also known as ECM Outputs. On the other hand, the
sensors and switches that provide inputs to the ECM are ECM Inputs. For example, the ECM adjusts ignition timing
based upon inputs it receives from sensors that react to : engine RPM, engine coolant temperature, throttle position,
transaxle gear, vehicle speed, etc. The ECM adjusts idle speed based on inputs it receives from sensors that react to :
throttle position,vehicle speed, transaxle gear, etc.

• Mass air flow sensor

The Mass Air Flow (MAF) Sensor is the most direct method of measuring engine load because it measures the mass
of air intake. This is also known as a "hotwire"
Sensor because it depends on the measurement of current flowing through heated wires to measure air flow. The hot
