Hello. What was the problem on your car? My 2009 Honda shuts off sometimes when on park or at a red light.

[@diegoa1126]

@@jorgehetnandez1696 have you fixed the problem?

[@rooseveltacook]

Thank you for the video. It totally helped me with my 2015 Mazda 6.

[@ashleelaplante3548]

I have an 09 Honda accord lx having intermittent hard start, check engine and vsa light comes on. Replaced, cat, starter, plugs, coils, crankshaft position sensor, and fuel pump. Then got a code for bad ecm. Every time i get a code and replace whatever the code is calling for it starts and drives great on the 1st try then shut it off and says theres a new problem 🤦‍♀️

[@daniellenelson9304]

I'm pretty much in the same boat w my 08 exl 🤦🏼‍♀️🙇🏼‍♀️

[@yocsmoke9252]

Can u put updated ecm relay on comments it says is currently unavailable please

[@zigzagtx]

That relay you have listed from Amazon will it also work for a 2007 Honda accord?

[@Monieapolis]

Thanks for the tip.

[@lewf5685]

[@badillofamily1833]

[@traceygilles7581]

I know this is a old video but my car is a 2009 Honda accord with the 3.5L v6 and it throws that code anywhere from 4,000 to 6,000 rpm but it’s like a cut

[@fredypineda57]

You ever fix it

[@rolandbrooks386]

Do you know where the ecm relay may be located on 1993 honda accord?

[@mohamadkilani2599]

Hello,Circuit Intermittent , sometimes when you starter the vehicle check engine going on with VSA, nothing different after update , already replaced the crank shaft , the problem is still , I try to take off the cable from cam shaft sensor and I drive the car. It's nothing gonna be happen no a check engine going on , the pcm has been delay to see I take of the jack from the sensor so what do you think the problem? Thank you.😂

[@ashleelaplante3548]

Did you figure out what the problem was? My 09 Honda accord does the same thing. Replaced, cat, starter, plugs, coils, crankshaft position sensor, and fuel pump and still having intermittent hard start, check engine and vsa light comes on

[@n5xgarage750]

What fixed it for you? Relay or fuse?

[@danteanderson9052]

I have a 2012 honda accord ex sometimes my engine starts blinking then i lose power accelerate very slowly can a pcm cause this problem?

[@gaelcarreno1094]

Hi I have a very similar problem and have the same car as you. Have you fixed the problem? If so was it the PCM?

[@Art-il2xf]

My main fuse keeps burn out after a while of driving Can you help me with any tips

[@nolovelost3981]

Mee too 08 accord mine blows out as soon as i turn the key went through 5. Looked for the shorted ground and nothing did u find the problem?

[@Noel127]

wiring issue

[@nolovelost3981]

Yea i figured it out wire was touching the frame behind the engine near the converter. Cam shaft sensor wiring

[@billwilson3665]
