What does an electrical load detector do?
The Electronic Load Detector (ELD) detects any electical load on the engine from accessories like A/C controls, radiator fan, lights, heater motor, etc. The ECU uses the ELD’s inputs to adjust alternator output and compensate for the additional electrical loads.
Where are load detector utilized?
Load sensors are generally used to determine the weight of an object (as in household or industrial scales), but they are also used to quantify tension (such as in pulley cables and ropes).
What is code P1298?
Error Code P1298 is defined as Electric Load Detector Circuit High Voltage. This means the ELD (Electric Load Detector) is getting high input voltage.
How is Honda eld diagnosed?
The ELD unit is easy to identify by its nondescript reddish-brown color. Also know that the ELD won’t detect loads that are attached directly to the battery.
What is alternator FR signal?
FR = Field Return signal. This signal provides information from the alternator to the PCM to indicate how hard the alternator is working (what percentage of capacity it is operating at).
What is the eld on a Honda Civic?
Honda’s answer to this is the ELD (Electrical Load Detector). This unit reads the amperage load directly from the battery and in-turn sends a varied voltage signal to the PCM which regulates the field signal to the alternator.
How do you know if a wire is load cell?
A load cell test is performed using a digital multimeter. The digital multimeter is connected between the positive signal wire and the negative signal wire of the load cell. The output between them should be equal or to a value specified in the datasheet. This is the test for load cell output resistance.
Which is the most common load cell used in the force sensors?
Explanation: Strain-Gauge based load cells are the most common load cell used in the force sensors. It is a transducer that is used for sensing the force, it converts the applied force into electrical signals which is used for sensing the amount of load that is applied. 2.
How do I fix my p1166 code?
Some of the most common repairs are:
- Repair short in the wire between A/F sensor relay and fuses.
- Repair open in the wire between the PCM and the A/F sensor 1 or Secondary HO2S sensor 2.
- Replace front O2 sensor.
- Replace faulty PCM.
What does eld do in Honda?
Since the early ’90s, Honda vehicles have used an electrical load detector (ELD) unit in the under-hood fuse/relay box. This unit reads the amperage load directly from the battery and in-turn sends a varied voltage signal to the PCM which regulates the field signal to the alternator.
What do all the wires on an alternator do?
Remote voltage sense alternators: The three wires connected to the alternator are the positive, negative cables and a third smaller gauge wire connected to the alternator remote sense or (S) terminal. To determine if your vehicle has remote sense, voltage will always be present on this terminal at all times.
