Can a bad ground cause low idle?

Can a bad ground cause low idle?

just to add, idle issues can be caused by poor grounds. if throws an offset to the voltage seen by the ECU, which either adds or pulls fuel. This either runs the engine lean or rich and the idle gets screwed up. It can result in slow cranking, unstable or low/high/surging idle, and a slew of other things.

What are the plugs on a Honda Civic?

This article applies to the Honda Civic/Del Sol (1992-2000). Each plug for each wire harness has one job – to remain securely connected. When these pieces fail, the electrical current will not reach the proper components, which results in ignition, idling, and driveability issues.

What happens when a 5V circuit is short to ground?

Based on test results, the 5V limiting resistor circuit design is more than just a simple resistor. The circuit can effectively minimize the amperage draw. This means that when a circuit becomes only partly shorted to ground, the voltage can be forced to drop between 1 and 4V.

What is the wire harness on a Honda Civic?

One of the most important components of an engine is the main wire harness. It routes all the electrical power required for each component and connects them with plugs. This article explains some common problems with wire harnesses and how to properly diagnose and repair them. This article applies to the Honda Civic/Del Sol (1992-2000).

Which is the low voltage side of the ignition coil?

The low voltage side of the system is referred to as the primary circuit. It includes the battery, ignition switch, primary coil winding, a triggering mechanism (such as a crankshaft sensor) and switching device (such as an ignition module or ECU). The high voltage side of the system is called the secondary circuit.

What causes Honda Civic engine harness to malfunction?

99-029 04-29-99: Malfunction Indicator light is on with blown fuse #15; Causes O2 and vehicle speed sensor (VSS) issues and dimming lights.

What to do if a Honda Civic harness plug melts?

Also, user errors, such as accidentally crossing the connections of a battery, can also cause the wire harness to melt. A broken wire harness plug is fixed with a simple replacement. Cut out the old plug, strip the wires, solder them to the new connector, and heat-shrink the connection.
