P0122 Throttle Position (TP) Sensor Circuit Low Input

P1298 Electric Load Detector (ELD) Circuit High Voltage

With a good service manual and a bit of skill you should be able to work on these yourself.

Hope this helps

P1298 and P0122. 0122 is a problem with the TPS throttle position sensor. P1298 I think it is air massflow sensor, not sure about the second one.

    Here you get the right codes:

    P0122 Throttle Position (TP) Sensor Circuit Low Input

    - replace the TPS



    P1298 Electric Load Detector (ELD) Circuit High Voltage


    The ELD measures the electrical load.Often, when you get an ELD error code this is because the ECU is detecting a short or an electrical overload caused by a different faulty part.

    Start replacing the throttle position sensor, and if you still get ELD error afterward, look for a short, starting inspection from your fusebox.

    I report my last post for better clarity:

    Here you get the right codes:

    P0122 Throttle Position (TP) Sensor Circuit Low Input

    - replace the TPS



    P1298 Electric Load Detector (ELD) Circuit High Voltage


    The
    ELD measures the electrical load.Often, when you get an ELD error code
    this is because the ECU is detecting a short or an electrical overload
    caused by a different faulty part.

    Start replacing the throttle
    position sensor, and if you still get ELD error afterward, look for a
    short, starting inspection from your fusebox.

    Follow up:

    I did some research on the Internet and found out that you get this two error in conjunction quite often on Hondas. See here for example.
    You usually fix it by replacing the TPS that costs about $30.

    Call honda, ask replacement price and also their opinion on this matter. To contact Honda in US call the toll-free number: 1-800-999-1009

1995 Honda accord ex v6 automatic transmission of code p1298


Electric Load Detector Circuit High Voltage

Possible causes - Faulty Electronic Load Detector Unit - Faulty Engine Control Module (ECM) - Electronic Load Detector Unit harness is open or shorted - Electronic Load Detector Unit circuit poor electrical connection
Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light)
P1298 Honda Description The Electric Load Detector (ELD) measures the main current flow and sends that signal to the Engine Control Module (ECM) to command the alternator charging system to get fuel efficiency and decrease the drag of the engine when starting.

My 1999 honda odyssey came out with code p1753 and code p1298 what does it mean


code p1298 refers to electrical load sensor--circuit/voltage high===causes wiring--under hood fuse box/relay plate--electrical load sensor--ECM programming---ECM

I would suggest taking it to a Honda service centre to have it checked out asap.

Code P1298 on 2001 honda odyssey


. Fuse number 15 in the under dash fuse box will be blown when you check it. This is caused by a shorted wire up under the intake manifold. HERE is some information on this and how to fix the problem. Once this is repaired your speedometer should work properly again. You may need to have the fault codes cleared after the repairs or just ignore the check engine light until it resets on its own which may take awhile.good luck

P1298 code


CODE P1298. ELD Circuit High Voltage.
Possible causes:
- 7.5 Amp fuse in under the dash fuse/ relay box.
- Repair open wire between 7.5 Amp fuse and ELD.
- Check for open wire between ECM/ PCM and ELD.
- Substitute a good-known ECM/ PCM and then recheck.

2004 - JEEP LIBERTY SPORT 3.7/V6 ENGINE LIGHT ON !!! CODE #(P0122) What is it ? Can I fix it ? Dealership fix only ?


P0122 Code - Throttle Position Sensor/Switch A Circuit Low Input

A P0122 code means that the the car's computer has detected that the TPS (throttle position sensor) is reporting too low a voltage. On some vehicles that lower limit is 0.17 - 0.20 volts (V).

Did you adjust it when you installed it? If the signal value is less than .17V then the PCM sets this code. Could be an open or a short to ground in the signal circuit. Or you may have lost the 5Volt reference voltage.

Symptoms may include:
* Rough or low idle
* Stalling
* Surging
* No/little acceleration
* other symptoms may also be present

Causes: A code P0122 may mean that one or more of the following has happened:
* TPS not mounted securely
* TPS circuit short to ground or another wire
* Faulty TPS
* Damaged computer (PCM)

Possible Solutions: Some recommended troubleshooting and repair steps are:
* Carefully check the throttle position sensor (TPS), wiring connector, and wiring for breaks, etc. Repair or replace as necessary
* Check the voltage at the TPS (refer to a service manual for your vehicle for specific information). If the voltage is too low that is indicative of a problem. Replace if necessary.
* If recently replaced the TPS may need to be adjusted. On some vehicles the installation instructions call for the TPS to be properly aligned or adjusted, consult a repair manual for specifics.
* If there are no symptoms at all, the problem may be intermittent and clearing the code may resolve the issue temporarily. If this is the case then you should definitely check the wiring to be sure it's not rubbing on anything, grounding, etc. The code may come back.


Hope helps (remember to rate this answer).

I have a 2004 Honda Civic 4 cyl. That has a code P1298 ''Manufacturer Control, Fuel/Air Metering''. This, I believe is causing multiple cylinder misfires. Can anyone tell me what the culprit is of the...


OK. Here's how to diagnose the P1298 error.

DTC P1298: ELD Circuit High Voltage

1. Reset the ECM/PCM (see HOW TO RESET THE ECM/PCM ).
2. Start the engine.
3. Turn on the headlights.

Is DTC P1298 indicated?

YES - Go to step 4.
NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the ELD and at the ECM/PCM.

4. Turn the ignition switch and headlights OFF.
5. Disconnect the ELD 3P connector.
6. Turn the ignition switch ON (II).
7. Measure voltage between body ground and ELD 3P connector terminal No. 1.

Is there battery voltage?


YES - Go to step 8.
NO - Check the No. 4 ACG (10A) fuse in the under-dash fuse/relay box. If the fuse is OK, repair open in the wire between the No. 4 ACG (10A) fuse and the ELD.

8. Turn the ignition switch OFF.
9. Connect ELD 3P connector terminal No. 3 to body ground with a jumper wire.

10. Disconnect ECM/PCM connector E (31P).
11. Check for continuity between body ground and ECM/PCM connector terminal E15.

Is there continuity?

YES - Go to step 12.
NO - Repair open in the wire between the ECM/PCM (E15) and the ELD.

12. Check for continuity between ELD 3P connector terminal No. 2 and body ground.

Is there continuity?

YES - Go to step 13.
NO - Repair open in the wire between ELD and G201.

13. Reconnect the ELD 3P connector and ECM/PCM connector E (31P).
14. Start the engine and let it idle.
15. While measuring voltage between ECM/PCM connector terminals A24 and E15, turn the headlights on (high).

Does the voltage drop?

YES - Update the ECM/PCM if it does not have the latest software, or
substitute a known-good ECM/PCM, then recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/PCM.
NO - Replace the ELD.
