The ESC computer sees the understeer event via the sensors long before the driver realizes it. Like an oxygen sensor or misfire monitor, specific criteria and number of events must be met for the system to activate. The other key inspection point is to look at the dash for any lights or messages.

Two factors govern all fuel injectors: pressure and time are used to calculate fuel flow into an engine. Pressure nor time can’t be used on their own to determine how much fuel the engine is using or to correct a wayward fuel trim number. The ECM can match the exhaust pulse to engine timing to determine the faulty cylinder.

Over the past 20 years, throttle-by-wire has become the standard technology on all gasoline engines. When the driver smashed the throttle to the floor, the air flowing through the venturis would cause more fuel to be sucked into the engine. First is the throttle body that controls the air entering the engine.

This strategy is about the safety of the total battery pack, such that it won’t allow the deteriorated pack to be overcharged or discharged and cause a thermal event or fire. Most codes that indicate the battery needs replacement will turn on the check engine light, and a message will appear in the information center.

A flashing check engine light and codes P0301 to P0308 are surefire indications that one or more cylinders are misfiring. The engine control module calculates the time between the edges of the crankshaft reluctor wheel teeth by receiving a signal from the crankshaft position sensor. Most monitors are pass or fail.

I n a perfect world, a flashing check engine light for DTCs P0301 through P0312 would always be solved by installing a new ignition coil. Also, replacing a single coil might not be the best approach to curing an engine of a chronic misfire. These misfires would set a DTC inside the engine computer.
