Car Forum / Honda Cars / May 200695 Civic LX Intake Air Temperature Sensor
Hi... Can any one please tell me whether a bad Intake Air Temperature Sensor (IAT) or a bad TW (Coolant Temperature sensor, or Water Temperature Sensor) will cause the engine not to fire up? I've read that these two sensors can affect injector pulse width? It seems that I'm getting too much fuel into the combustion chambers, thus after a few cranks of the engine, the combustion chambers are flooded (spark plugs soaking wet with fuel) and the engine won't start. The spark plugs do produce strong sparks. So I'm quite sure it's not an ignition problem. Iit seems like more fuel than necessary is injected - that's why I'm wondering whether a bad IAT or TW can cause this problem. Thanks. > Hi... > > Can any one please tell me whether a bad Intake Air Temperature Sensor > (IAT) or a bad TW (Coolant Temperature sensor, or Water Temperature > Sensor) will cause the engine not to fire up?

Is the spark properly timed?  SignatureTeGGeR® The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ Has anyone bought an Oxygen sensor from this company? They have the best price I've found for a direct replacement on my 94 VX. I see the NTK oxygen sensor for a 94 Civic VX for $80 at this site. But I don't think that's a genuine Honda sensor, and so it's a real roll of the dice. Try https://www.automedicsupply.com for OEM sensors at good prices. I have used it for an OEM O2 sensor for my 91 Civic a couple of years ago. Good service. No problems with the sensor.

My red jewel is a Canadian built 48 stater. This is the one I'm looking at. It has the correct Honda part number. Most sites want $300 + for it. www.oxygensensor.net/parts/o2parts/L1H1.html > Has anyone bought an Oxygen sensor from this company? > They have the best price I've found for a direct replacement > on my 94 VX. try autohausaz.com I bought a Walker O2S for 78.00 USD with free shipping.

Jim, How long has this Walker been in use? Any problems? >>>> Has anyone bought an Oxygen sensor from this company? >>>> They have the best price I've found for a direct replacement [quoted text clipped - 9 lines] > > How long has this Walker been in use?

I'd like to have enough to cover any quick fix situations. I've come up with : Combo screwdriver, my small ratchet & a few sockets (which ones most usable for a Civic?), medium Channellocks. So, what do the rest of you carry? > I'm trying to put together a small tool kit.

I bought a $10 metric socket/wrench and magnetic-bit screwdriver set from Big Lots,it works great,except I had to junk and replace the ratchet.It even has a needle-nose pliers. SignatureJim Yanik jyanik at kua.net I can't check the ignition timing, since the engine doesn't run. Is there a way to check ignition timing without the engine running? Thanks. > I can't check the ignition timing, since the engine doesn't run. Is > there a way to check ignition timing without the engine running? > Thanks. Yeah, have someone crank while you test. Same as if it was running, but cranking instead. Timing ought to be close to the specified 16deg BTDC. Another method: Turn engine by hand to TDC compression (#1 valves closed), then remove distributor cap and see if rotor arm is pointing at the #1 terminal on the cap. That will give you an idea whether the timing's horribly off or not. Are you sure your timing belt hasn't slipped? SignatureTeGGeR® The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ |
