Can a bad ground cause a sensor to fail?
For instance, just because a sensor appears to have failed doesn’t mean it’s the sensor. “It could easily be the wiring to the sensor, a connection or a bad ground somewhere else in the system,” says Charlie Groeller, a retired electrical engineer formerly with Mack Trucks.
What to do if your car electrical connector is corroded?
Pull the male end from the female receiver. Make sure you are grabbing the male end by the plastic of the connector and not the wires. If your connector is heavily corroded, spray a little bit of DeoxIT D5 Connector & Contact Treatment on it and wait for 5 minutes to let it penetrate and then pull the connection apart.
How much does a battery sensor Connector cost?
I found it! $13.59 Three different Ford Dealer Parts Counter men and a Parts Manager could not find this connector!! Finding this was like, finding a needle in a haystack! this connector is part of the engine wiring harness which costs over $800.00 plus lots of labor!!!!!!!! “Sensor- Battery Current” This sensor/connector gives feedback to the BCM.
What’s the best way to disconnect an auto connector?
If one is present, hold the female end in one hand and push down or in on the locking tab to release it. If there is no tab, hold the female end firmly in one hand. Pull the male end from the female receiver. Make sure you are grabbing the male end by the plastic of the connector and not the wires.
How to prevent a DC connector from corrosion?
This type of corrosion will only happen in the presence of moisture and a DC current and generally on the negative terminal. (electrolysis) To prevent it, you need to prevent the moisture getting to the connector. This can be done using a plastic tube around the connector with cable ties and some desiccant.
For instance, just because a sensor appears to have failed doesn’t mean it’s the sensor. “It could easily be the wiring to the sensor, a connection or a bad ground somewhere else in the system,” says Charlie Groeller, a retired electrical engineer formerly with Mack Trucks.
What to do if your ECM connector is corroded?
Disconnect all three ECM connectors – X1, X2 and X3 – from the ECM and remove the terminal guide (Fig. 17) from each connector so all the metal terminals can be seen. Use a bright light to inspect all the terminals in all three connectors for green corrosion, coolant or oil.
How are watertight electrical connectors used in the underground?
Filled with silicone, these connectors seal out moisture and prevent corrosion. Suitable for use underground, these connectors consist of a twist-on wire connector and an abrasion- and moisture-resistant insulator tube.
