What would cause a 2004 Honda Accord dx. 4 cylinder to keep throwing the PO141 & PO341 even after those parts have been replaced Po141 & PO 341
You have to either clear the codes with your scanner or drive for multiple "drive cycles". Those codes are stored in the ECU now so even if the sensors are working okay the ECU understands that some glitches are temporary but still needs to be "told" it's been really fixed.
The exception to this is doing drive cycles but I only think these apply to emissions related codes and yes, those fall under emissions (the engine isn't operating at the optimal condition for emissions). An example of this is a loose gas cap. After you tighten it properly, the owners manual or a dealer will just tell you "keep driving it, it will go away", i.e. drive cycles. Yeah, or you could go to Autozone and have them clear it or you.
When my Honda VTX is hot it stops going
If your 2002 Honda VTX 1800 loses power to the wheels when it gets hot, it could be due to several potential issues. Here are a few possible causes to consider:
- Overheating: Check the cooling system of your motorcycle, including the coolant level, radiator, and cooling fan. If the engine is overheating, it can lead to loss of power. Ensure that the cooling system is functioning properly and that there are no blockages or leaks.
- Fuel delivery issues: When the engine gets hot, fuel delivery problems can occur. Check the fuel system components, including the fuel pump, fuel filter, and carburetors (if applicable). Make sure they are clean, free from clogs, and functioning correctly. If necessary, clean or replace these components.
- Ignition system problems: Heat can affect the ignition system, leading to weak spark or misfiring. Inspect the ignition coils, spark plugs, and spark plug wires. Ensure they are in good condition and properly connected. Replace any worn-out or damaged components as needed.
- Exhaust system obstruction: A partially blocked or restricted exhaust system can cause a loss of power when the engine gets hot. Inspect the exhaust pipes, mufflers, and catalytic converter (if equipped). Look for any obstructions, such as debris or carbon buildup, and clean or remove them.
- Clutch issues: If the clutch is not engaging properly when the engine is hot, it can result in a loss of power to the wheels. Check the clutch assembly, including the clutch plates, springs, and cable (if applicable). Ensure that the clutch is adjusted correctly and operating smoothly.
- Electrical problems: Heat can affect electrical components, leading to intermittent power loss. Inspect the wiring harness, connectors, and electrical connections. Look for loose or corroded connections, damaged wires, or faulty components. Repair or replace any problematic electrical parts.
- Engine performance issues: If none of the above issues are present, it's possible that there could be internal engine problems causing the loss of power. In this case, it's recommended to consult a qualified motorcycle mechanic or Honda dealer for a more thorough diagnosis and inspection.
Remember to follow proper safety precautions and consult the service manual for your specific motorcycle model during the troubleshooting process. If you're not confident in diagnosing or fixing the issue yourself, it's best to seek professional assistance to ensure a proper and accurate resolution.

Honda Cr-v 2003....engine light came on, misfire under load, went into limp mode. It is showing codes1298 and 1279. Are these connected, i.e does the ELD cause a misfire which results in 1279 code
if you drive any car this new.
and with head lamps on
and see the lamps dim
and the alternator is failing EDL and all.
even fan belt loose. battery lugs loose.
the 14vdc (typ) batter voltage falls fast to 12vdc then near 10vdc.
lamps now dim the EFI starts to fail. (its computer, and will not run below 10vdc. or even misfires) or under injects, and well a list of random things. all wrong.
test the battery first many a bad battery can cause horrible crazy things as you bounce down a road. and the battery cane make the alternator or eld go nuts.
13vdc to 15vdc is normal at the battery lugs engine running'
own a voltmeter to learn this?
misfires has many causes, above is but 1 of 50
above is battery charger failures.
the 2003 car we an scan the PCM to see errors too
cars this old tend have 2 or more hard errors.
but all ELD tests are in the book, to read;.
ELD is like smart device the helps keep battery from going dead.
ELD prevents overharge and under, better than most cars made.
the ELD is a ammeter,(converter)
the PCM asks over and over (looped) what does the battery see (here)
current. so that allows the PCM to control the Alternator in a better way,to not stress the battery and get a longer life.
the problem we see is kids with 2000watt bridging ear killing watts
added, and the ELD does not see that current (HACKED IN by owners)) so the battery is not properly charged and goes bad fast.
so don't by honda's(sorry) or rip out the stock alternator and stand alone version installed.. (or ask honda how to do it right?)
those are the problems , if still stock ignore my AMP'd up hacks.
I have a 2008 Honda accord coupe V6 I am unable to find the flasher relay because my blinkers are not working Can I get some insight on where it is located?
no country told, but ours, (USA) has this car starts and drives ok, and all electrics work , headlamps and parking lamps? blinkers dead on all 4 corners of car , not told, for all.? hazards fail too ,all 4 corners/???? all fuses good? scan the OBD2 port under dash for errors? the cluster 2lamps Left and right dead?, and the sounder beep dead too (turns)? the turns module is part of under dash,fuse box. nobody installed wrong lamps outside corners of car , right? does rear of car have trailer hitch hacks? (shorted) fuse9 and 15 under hood not blown? fuse 5 under dash driver box fuses good??(kick panel) check for damage on all 4 corner lamp socket/wirescheck for damage not repair from previous collisions.to wiring and lamps. and inspection is first'wiring and fuses. as seen here
After replacing motor mounts on 2002 honda accord se 4 cyl it starts but revs up and down when given throttle
erratic up and down idle is usually either a faulty idle air control valve, located on throttle body, or vacuum leak.
Check vacuum hoses by spraying each one with carb cleaner while engine is idling. If idle smooths out when one is sprayed, then replace that vacuum hose.
If all are ok, then the IAC valve is bad. This is replaceable by itself. But before replacing it, try pulling it and cleaning the ports out of any carbon deposits
It runs about $144.
2001 Honda Accord dies randomly but will start again after time has passed. Is this because of a faulty cam sensor??
Hi Ciara Kilgore, are you asking
for us to guess.
or how to do tests that find the 50 causes of dead or stalled engines.
wow a Tee boned car, first one posted like here ever.
amazing post. what are you asking the blind.
D4 lamp (is a huge clue)
what country is this car located or sold to first.
D4 light is like a check engine light for the transmission
it means it is failing.
your forgot to say the D4 lamp is in
the
not told what no start means
1: will not crank , the starter motor is dead.
2: cranks fast the starter motor but the engine fails to start , run and stay running.
D4 shows flash codes on old honda's
when D4 happens, shift the transmission
too all gears and back to park see if engine starts now
2001, we scan the PCM using oBD2 scan tool
all shops know how to do that. ask them to.
on another NOTE
call the guy insurance co. that hit your car
the fix it like new (or total it)
end story. do that now.
D4 is honda magic for
DRIVE, the drive lamp flashes when
the tranny fails. and did and crashes to wreck wires. to lots of things. and more.

NOW I READ THE SERVICE MANUAL TOO YOU
ON #7 FEED
as you know Honda loves to call things by the wrong ASE/SAE NAMES. (NON STANDARD)
FUSE 78 RUNS A HUGE PILE OF THINGS.
9 THINGS, 4CYL, AND 9 THINGS V6
HERE THEY ARE,.
TO FIND IT MAY TAKE PULLING 9 THINGS
THE O2 SENSOR HEATER SHORTED TOPS MY LIST OF LOVE TO SHORT OUT. RED CIRCLE IN THE SCHEMATIC.
