94729647

  1. Measure voltage between ECM/PCM connector terminals A1 and A24, 30 seconds after the ignition switch is turned ON (II).
Is there battery voltage?

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 - Go to step 5.

94729648

  1. Measure voltage between ECM/PCM connector terminals A22 and A24.
Is there battery voltage?

YES - Go to step 6.

NO - Go to step 10.


  1. Turn the ignition switch OFF.
  2. Disconnect ECM/PCM connector E (31P).
  3. Turn the ignition switch ON (II).
94729649

  1. Connect ECM/PCM connector terminal E8 to body ground with a jumper wire, then measure voltage between ECM/PCM connector terminals A1 and A24.
Is there battery voltage?

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 - Repair open or short in the wire between the A/F Sensor (Sensor 1) and ECM/PCM (A1).


  1. Turn the ignition switch OFF.
  2. Disconnect the ECM/PCM connector A (31P) and the A/F Sensor (Sensor 1) 4P connector.
94729650

  1. Check for continuity between the A/F Sensor (Sensor 1) 4P connector terminal No.3 and body ground.
Is there continuity?

YES - Repair short in the wire between the A/F Sensor relay, A/F Sensor (Sensor 1) and ECM/PCM (A22).

NO - Go to step 13.


  1. Turn the ignition switch ON (II).
94729651

  1. Measure voltage between ECM/PCM connector terminals E8 and A24.
Is there battery voltage?

YES - Repair open in the wire between the ECM/PCM (A22) and the A/F Sensor (Sensor 1).

NO - Go to step 15.


  1. Check for continuity in the wires between the A/F Sensor and the fuses.

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.

Where is the PCM located on a 1991 Oldsmobile 98 Regency elite?


The PCMor powertrain control module is only on 1996 and newer cars.Earlier models have a ECM or electronic control module/pcm.You want to change the ECM if its a 1992.Its located under the right hand side of the instrument panel.The ecm has a prom( programmable read only memory)in it.You will need to remove this from the old ecm and install in the new ecm.The ECM/PCM can be used in many different GM vehicles but the prom is very specific and must be used only in the vehicle it was designed.The prom will not come with the new ecm and must be carefully removed and installed on the new ecm.There also is a CALPAK in the ECM ( A devise for fuel delivery) This may come with the new ECM But make sure all parts are the same.You should get a vehicle repair manual to do this job correctly,and make sure you do not damage your PROM.Your PROM is very IMPORTANT!
