Car Forum / Honda Cars / June 200691 civic crank angle senor
i recently did a head gasket on this car and replaced the timing belt. upon successfully starting the car and adjusting the valves, i took it for a drive. at idle it runs fine. about 2 minutes into the drive (not sure if this is time or speed related) the check engine light would go on simultaneously as the car would lose power - as though a cylinder stopped firing. after getting home, i check the ecu. it claims a crank angle sensor fault. this is located in the distributor, which is only a few months old, and is unreplaceable according to chiltons. if i clear the code by pulling the hazard fuse for 10 seconds or so, the car starts up and runs great. again, it idles fine, take it for a drive, about 2 minutes later, bam, check engine and power loss. now, the ecu has been known to be wrong before. any ideas? thanks so much. > i recently did a head gasket on this car and replaced the timing belt. > upon successfully starting the car and adjusting the valves, i took it [quoted text clipped - 16 lines] > > thanks so much. ----------------------------------- Did you put the 'heat sink' paste on the backside of the components that need it? Sounds like a heat buildup problem . . .

Sounds like a heat buildup problem . . . ---------------------------------- If somebody failed to put the heat sink paste (same as what's used on Pentium chips) when they assembled the components inside the ( new / used / reconditioned????) distributor (which was installed when the weather was cooler) you might be getting overheating problems / circuit shutdowns. Do a google groups search. 'Curly' yes, the distributor was remanufactured from Napa. i'd assume they assembled it correctly. i am not so sure i want to take it apart to find out... i think i will take off the cap and see what i can see... > > i'm unfamiliar with what you're talking about. could you enlighten me? > ------------------------------------------ [quoted text clipped - 11 lines] > > 'Curly' > yes, the distributor was remanufactured from Napa. i'd assume they > assembled it correctly. i am not so sure i want to take it apart to [quoted text clipped - 13 lines] > > weather was cooler) you might be getting overheating problems / circuit > > shutdowns. Speaking for the crank sensor, I wouldn't put heatsink paste on the crank sensor since it works best if it's isolated from the housing. > larson.joshua@gmail.com wrote: >> [quoted text clipped - 35 lines] > components that > need it?
