 Posted: Thu Mar 06, 2008 10:02 pm Post subject: Ticking noise from ECU |
 |
|
I had a look through a lot of posts, but couldn't find anything relating to this problem.
About a 2 months ago, I disconnected the ECU to confirm which wire goes to the instrument cluster when I installed a Speedo Corrector. The car has been off the road till last week. Now, every time I accelerate, there's a ticking noise coming from the ECU. Definitely, not the injectors making the noise.
I can't remember if I disconnected the battery when I fiddled with the ECU. Does anyone know if this would have caused something to short out inside? How sensitive are the ECUs to power surges? |

I've experienced a similar problem, and No, theres no Relays or any 'moving' parts in the ECU.
I went on a rampage to find it, even removed the glove box (it sounds like moving pens doesn't it)
I put it down to something in my interior fan and lets leave it at that! |

Mine has always made this noise. Thought it was an intake noise coming in through the air vents  |

there is nothing in the ecu that ticks, well... unless you can hear silicon tranistors clicking.
the ecu does not click, it'll be the fan, derbis, even some engine bay valves.
or as above, someones on gas and they've installed a relay. |

mine has this vacuum solenoid thing that was rubber mounted but the rubber had broke and was pulsating on metal which made a ticking noise which eminated through the left hand guard into the left hand kick panel which is where the computer is on a EB |

I have to agree with Krytox. I was sure a ticking noise was coming from the ECU until I pulled the cover off it and left it freestanding. After driving around for a while, I found that the noise from sticking lifters somehow resonates in the left guard (in the vicinity of the ECU).
I suppose the noise from the extractors masks the sound on the driver's side of the car. Although the noise is not apparent when you have the bonnet up, it's noticeable when you're in the car accelerating.
I think it started after putting in extra shims for a Wade cam and I'm pretty sure some of the lifters were hard to reinstall. Looks like the rockers need to be pulled apart and reassembled.
Anyone else found 'ticking noises' started after they replaced their cam? |

Gents..
I just picked up my AUIII Fairmont Ghia, purchased from Etheridge in VIC> The car started ticking off and on after around 5 minutes, from what appeared to be the ECU. Took it straight back to the dealer. They went inside and quizzed a mechanic. Rapid ticking appeared to be a Charcoal Canister Purge Valve. This is located behind the covers under the Panels near the LH Headlight. I am off to Carmichael Ford in Townsville to verify if it is the part, the wiring, the ECU or a combination of either or all to sort something out with the warranty. If it is big enough $1600 cartage back to Melbourne. They assured me it was fine. Otherwise it would have been left with them to rectify under the warranty.
Let me know if this gels with any other members. Will update tomorrow.

My Aug '98 EL Futura 6 cyl auto, not on gas, did it for most of the years I had it. Only ticked when the engine was under load and accelerator was down by any setting. Didn't do it when rolling along with no throttle.
No-one could identify it, appeared to be harmless though, and I suspected it was a fan. Annoyed the hell out of me. I used to turn the CD volume up a bit more! |

Took off the under body cover screws, peeled it back, then started the car. The ticking/clicking started a few minutes in at idle. There is an electronic servo/valve fed by a two wire connector and a t-piece with an in & out of vacuum type hose. It was clicking away. Moved it away from the body and the noise subsided somewhat. Wrapped it in loose cotton and then cable tied it. I would not anticipate any problems with heat. It is still ventilated under there. IF the paint bubbles behind the left headlight and a warning light or two start up I will know where the problem lay. I had been told the $160 replacement part may start ticking as soon as it is fitted. Annoying noise gone...If I could two arms up there I would have disconnected it completely, monitored fuel consumption etc and then decided whether my non-compliance with EPA laws annoyed me more than the ticking...Problem solved...for now..

Well i had something similar though it wasnt the ECU but the BEM.
My whole interior is out so i went to plug just the loom back in so i could start my car. (but no dash, just the wiring)
Plugged everything in (i thought i did) and without even turning the key i heard the BEM ticking.
I have started my car this way several times before and had never heard this ticking.
A minute later i realised i didnt connect the ground wire with the green screw that belongs in the middle, behind the dash near the windscreen.
As soon as i screwed that back into the metal the ticking stopped.
Just to make sure, i pulled it back off and the ticking started again.
Hopefully its that simple for any of you. Maybe a ground wire or any other wire has come loose?
Or has anyone played with any of the wiring around the ECU?
But maybe my case was different considering it was the BEM and not the ECU. |
