That is the signal that you want the computer to start the engine by energizing the ignition circuit.
FYI, On a OBD2 system, the ECM can detect a misfire in the firing order by looking at the increased speed of teeth passing the crank sensor. If the ECM doesn't detect a slight speed increase in the frequency of teeth passing the sensor, it knows that that cylinder didn't fire. In other words, it is looking for an increase in the crankshaft speed each time a cylinder fires.

Where is the ecu temperature sensor on a 2002 S-10?
Need to know what engine you have.
VW Ahu engine need an ecu?
Yes, the VW Ahu engine requires an ECU (Engine Control Unit) to manage its operation. The ECU controls various engine functions, including fuel injection, ignition timing, and emissions. Without a functioning ECU, the engine may not run properly or at all, as it relies on the ECU for optimal performance and efficiency.
Will camshaft position sensor keep from cranking if got wet?
Yes, a wet camshaft position sensor can prevent the engine from cranking. Moisture can disrupt the sensor's ability to accurately read the camshaft's position, leading to incorrect timing signals sent to the engine control unit (ECU). If the ECU does not receive the proper signals, it may disable the starting system to protect the engine. However, the extent of the impact can vary depending on the specific vehicle and the severity of the moisture exposure.
Does a 1997 corsa merit have an ECU?
Yes it has, all injection engines need an ecu to be the brain for making the engine run efficiently.
Do you need an ecu for a 1991 dodge stealth?
Yes, the computer is required to run the engine.
Can you swap a turbo engine for a non turbo engine in a 92 eclipse?
Yes you can you will need to get the non-turbo engine, non-t ECU and wire harness. The wire harness and ecu are diffrent between the t and the non t.
Can you put a 2.2L turbo engine in a 1994 Chrysler LeBaron?
of course you can i mean the engine bay allow it but you need to install the ECU and engine/injectors/ecu arnes as well and if you ,re going to swap from automatic to manual you'll need the transmission shock too. good luck!
Anyone know where a good online store is for a ecu i have a 1988 Chevy cavalier and i need a ecu for it2.8-3.1?
Ebay or the Salvage yard
Lincoln mark 8 ecu?
ecu= engine control unit
Does a car run when ecu is unplugged?
Assuming you mean the engine ECU, the answer is no
Where does the cold start injector get its pulse on a 1992 E 300 4matic?
In a 1992 E 300 4Matic, the cold start injector receives its pulse from the engine control unit (ECU). The ECU monitors engine temperature through the coolant temperature sensor and activates the cold start injector when the engine is cold, providing additional fuel to aid in starting. This process typically occurs during the initial cranking of the engine to ensure smooth ignition under cold conditions.
Can you swap a eclipse turbo engine into a 1991 Mitsubishi mirage?
yep need a dif ecu though
