DC5 Technical Problems/Issues

[Vagabond]

Bro Vagabond, sorry for being a noob, but whats a TP sensor n what does it do? :hmmmm: U've experienced the same problem before too?And if its the TP sensor, what price tag am I looking at for a replacement and where to get it/change it? Thanks for your advice bro. Cheers

Throttle position sensor. the TPS informs your ECU on how wide the throttle plate is open, and thus the ecu regulates the right fuel mixture, fuel cut off, etc.

errors with the TPS can cause symptoms such as:
a) CEL
b) jerky acceleration or deceleration - you'll feel like the engine is straining but doesnt seem to want to go (acceleration) and sudden jerks when slowing down , due to fuel cut-off (deceleration)
c) poor fc


the american's have good ways to test whether a TPS is faulty or not, the best way to diagnose would be to hook the TPS up to an osiloscope , feed it a 5v input, simulate the potentiometer from throttle fully close to WOT and check the sinosoidal wave output on it's gradient.

for original honda/keihin 2nd hand tps, its from rm350 and above
while aftermarket new ones (mostly american made) goes for rm250 and above, if not mistaken.

Hi guys, I have an issue whereby after I vtec there is rattling sound like something is loose coming from my accelarator pedal. I will only hear this sound when I lift my foot of the pedal. Had checked all the nuts and bolt are tighten. The sound is coming from inside the engine bay. it doesn't effect the performance but it's bloody annoying. Anyone experience this before? Cheers ..

have you checked your power steering hose mounting bracket??

open up the engine hood, look at the valve head cover.
the power steering hose is mounted / held in place by a bracket secured to the valve head cover.
there are two possible bracket positions for the hose, and the bracket itself is quite soft and bendable. it's possible that during deceleration, it comes into contact with either:
a) aftermarket engine tower bars
b) the valve head cover itself.

just bend the bracket to make sure that there is no contact with any possible points during engine vibration. clearance between metal points should be at least 10mm.

Thanks a lot for your useful information bro Vagabond

Btw, whats CEL? I have the b) issue and in terms of FC, im doing appr. 400++km with a full tank, city drive, is that consider poor FC bro? Any suggestion of where should I go for the diagnosis? for the TPS issue? Also, does it make a lot of difference for ori Honda TPS compared to American ones? Any suggestion of where to get the after market TPS? Appreciate much of your advices

yea i think i having the same issue, only let go pedal will hear the sound..but they say is normal..coz of the gearbox i think..not sure.

Thanks for the info bro. But it cannot be the power steering bracket as when I put my foot to the pedal the sound actually dissapeared.. It became apparent when I lifted my foot of the pedal. something is vibrating through the pedal.

Bur anyway, it' worth the try I will tryit out..

i'm not talking about the power steering bracket la bro ..... it's the bracket holding the hose from the top of the alternator to the power steering ..... there are two different mounting points there.
the vibration that cause the bracket impact occurred during accelerator lift off.

alternatively, it could be a faulty engine torque damper if you've got one installed

400+KM city driving sounds alright actually.
CEL = check engine light
Honda/Keihin TPS have much better connecting wires/terminals to the potentiometer inside the TPS, as compared to the american aftermarket ones: omni, obx, etc.....

Found the culprit that been causing the rattling sound...according to the mech.. there is shaft going out where the throttle cable is .. the cable is rattling.. he put some greese and no more sound..

which shaft is that?

 

[GTI4740]

which shaft is that?

Quite frankly I didn;t see it.. it must be the one leading out to the firewall.. What ever the mech did it has dampen the sound a bit.. can still hear it but not as loud as before..

hey just wanna check....do any pre-facelift guys experience this problem when shifting gears.

sometimes (not all the time), when you punch the clutch and shift from 2nd to 3rd (happens from 1st to 2nd sometimes), the gear knob sort of "POPS" out instead of transitioning smoothly?

its weird that the type R gearbox is so sensitive and theres crunching as well.

hii guys just got my dc5 fcl lately.Anyway got problem with my fuel meter. During starting the car, the meter indicated at the normal fuel level, but when cruising the meter start to drop slowly almost 3 bar. When i stop the car the meter start going back to normal...have anyone got this prob..

my dc5 last time does sometimes give out that weird 'pop' and crunch(which is normal among other dc5's i guess) but never ever had any problems regarding with the gearbox..i thought i was the only one having this kind of stuff:hmmmm:..however, it only happens to me during high revving and quick-shifting..other than that, gear transitions are smooth..

it happened to me sometimess during revving high rpm from fourth to fifth gear. Anyways, others are good..i thinks its normal.

I experienced the same thing. When i first test drove my car, I thought the gearbox/synchros had issues. Test drove a few other DC5s, then I realised its pretty 'standard'.

So, I think its normal.

ahhh then i guess im not the only one with the issue then....puts my mind at ease...

dont want it ending up costing me a bomb coz i ignored it and fucked my synchros

Guys, its time to change my serpentine belt(altenator punya belt).
Where i could find it and how much it cost?
FD2R punya belt can fit DC5 or not eh?

The belt wont cost u much plus its easy to source....U can ask ur regular workshop to replace and order it OR get it urself at any honda spare part shop..
