How do I fix code p1298?
Some of the most common fixes are:
- Replacement of the Electric Load Detector.
- Update or replacement of the PCM.
- Repair open wires.
- Repair or replace Open or shorted Electric Load Detector records.
- Repair poor electrical connection in Electric Load Detector Circuit.
What does the electronic 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.
What is eld on CRV?
Hondas have a device in the fuse box called a Electronic Load Detector (ELD). It works with the car’s computer (PCM), which controls electrical output current to the car’s battery.
What is an ELD unit?
The ELD unit monitors amp flow to determine the vehicle load conditions. The PCM uses data from the ELD, engine RPM, Vehicle Speed, Coolant Temp, Air Temp etc. to decide if the generator should operate at 12.6 volts, or at 14.5 volts.
What is P0420 Honda?
Most of the time, code P0420 indicates a faulty catalytic converter. There are, however, instances where a bad oxygen sensor can trigger the code. Monitor the sensors with a scan tool. The sensors should go rich in response to the propane.
What is a Honda ELD unit?
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.
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 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 does the ELD do Honda?
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 does a Honda charging system work?
How the two-wire Honda charging system works. The ECM/PCM gathers data from the various sensors including the ELD and determines the required charging rate. Based on that data, the PCM commands the alternator to provide a specific charging rate (voltage) between 12.5 and 14.5 volts, using 0.1-volt steps.
What does p1298 mean on Honda Charger?
If your Honda vehicle has stored a code P1298, it means that the powertrain control module (PCM) has detected a problem with part of the charging system known as the electronic load detector (ELD) or ELD circuit. This code specifically pertains to a condition in which a voltage signal that is higher than anticipated has been perceived.
How to reset the p1298 load detector code?
Connect the scanner to the vehicle diagnostic connector and retrieve stored codes and freeze frame data. Write it down as it will almost always come in handy if the diagnosis drags on due to an intermittent condition. Clear the codes and operate the vehicle under various electrical load conditions to see if the code P1298 is reset.
What does error code p1298 mean on Eld?
Error Code P1298 is defined as Electric Load Detector Circuit High Voltage. This means the ELD (Electric Load Detector) is getting high input voltage. This error code is a manufacturer-specific trouble code, meaning it does not appear to all vehicle makes and models with OBD-II system or vehicles made since 1996 up to present.
When does a PCM get a code p1298?
If the PCM detects a voltage signal from the ELD circuit that is greater than the degree of voltage it expected the alternator to produce at a given time and under a specific set of circumstances, a code P1298 will be stored and a malfunction indicator lamp (MIL) may be illuminated. What are the common causes of code P1298?
