Acura Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome. My name is ***** ***** you for visiting the site.
If you accept my additional service request for your email address, you can give me your email in a private info box and I'll send you the test instructions in a PDF file, the file is rather large.
You will just have to accept the additional service offer and ENTER your email address in the “ENTER CONTACT INFO” section so that I can see it. Thanks
I do not have access to your email address,
I might be able to put the test in my dropbox as a PDF.
Let me just say that any money that you paid, or if you have a subscription, that money stays in your account until the answers are rated, (positive) regardless of how fast or how long it may take to get finished. You can FOLLOW UP AT ANYTIME, even after rating.
I have the test instructions in a PDF format, at the following link. You can copy and paste it into a new browser and rate the answer on this page. Thanks
Please don’t forget to rate the answer in a positive way, . EVEN IF YOU HAVE A SUBSCRIPTION ****THAT IS THE ONLY WAY I GET PAID ****
It is showing that you are waiting for me. Let me send this as a test, thanks
Normally we get paid for the original answer(s) before any follow ups, but a blown fuse won't give you that trouble code, it has nothing to do with the "car's service manual" and it's probably just a bad IMRC actuator or valve. In fact according to the test the resistance is too high on the reading, (B/C) that you stated, thanks
I am sorry but after reviewing your history I am no longer able to help with it, thanks
YOU CAN FRY THINGS IF SHORTS A CURE BUT TRY THIS FIRST DTC P1077: IMRC SYSTEM MALFUNCTION (LOW RPM)
Special Tools RequiredVacuum pump/gauge, 0-3 in. Hg A973X-041-XXXXX1. Reset the ECM/PCM.2. Start the engine, and hold it at 3,000 RPM with no load (in Park or neutral) until the radiator fan comes on. Is DTC P1077 indicated?YES - Go to step 3.NO - Intermittent failure, system is OK at this time. Check for poorconnections or loose terminals at the intake manifold runner control(IMRC) solenoid valve and at the ECM/PCM.3. Disconnect the vacuum hose (A) from the intake manifold runner control (IMRC) actuator (B), and connect a vacuum pump to the hose.Is there vacuum with the engine at idle?YES - Go to step 11.NO - Go to step 4.4. Check the vacuum hose between the IMRC actuator and IMRC solenoid valve.Is the vacuum hose OK?YES - Go to step 5.NO - Repair the blockage or vacuum leak between the IMRC actuator andIMRC solenoid valve.5. Disconnect the lower vacuum hose (A) from the IMRC solenoid valve (B), and connect a vacuum pump to the hose.Is there vacuum?YES - Go to step 6.NO - Repair the blockage or vacuum leak between the intake manifold and IMRC solenoid valve.6. Reconnect the lower vacuum hose to the IMRC solenoid valve, and connect a vacuum pump to the vacuum hose (A).7. Disconnect the IMRC solenoid valve 2P connector.Is there vacuum?YES - Go to step 8.NO - Replace the IMRC solenoid valve.8. Turn the ignition switch OFF.9. Disconnect ECM/PCM connector B (24P).10. Check for continuity between IMRC solenoid valve 2P connector terminal No. 2 and body ground.Is there continuity?YES - Repair short in the wire between the ECM/PCM (B22) and theIMRC solenoid valve.NO - Update the ECM/PCM if it does not have the latest software, orsubstitute a known-good ECM/PCM, then recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace theoriginal ECM/PCM.11. Turn the ignition switch OFF.12. Connect a vacuum pump to the IMRC actuator (A), then apply vacuum.Does the IMRC actuator hold vacuum?YES - Go to step 13.NO - Replace the IMRC valve assembly.13. Disconnect the IMRC valve position sensor 3P connector.14. At the sensor side, measure resistance between IMRC valve position sensor 3P connector terminals No. 2 and No. 3.Is there about 9.5 kohm at room temperature?YES - Update the ECM/PCM if it does not have the latest software, orsubstitute a known-good ECM/PCM, then recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace theoriginal ECM/PCM.NO - Replace the IMRC valve assembly.
THIS IS THE INTAKE MANIFOLD RUNNER VALVE , IT'S LOCATED OVER THE ALTERNATOR ATTACHED TO INTAKE MANIFOLD. QUITE A JOB IF YOUR NOT MECHANICALLY INCLINED
