HELP!! CEL : Code 43
EDIT: I pulled the code again today because this time my car threw a code at 40mph. This time it was code 43 and not code 4.
Hey, so I've been getting the Crankshaft Position Sensor CEL ever once in a while, normally when I'm accelerating hard onto the freeway. I went to pull the the first time and pulled it but didn't clear it yet. I then started my car (93 civic coupe) and it was cleared. So wtf?! I have now been clearing it on the freeway by turning the car off and back on at 70mph, properly, that is. So, why is it clearing itself? And, is this just that the sensor is going to crap? Thanks!!! |

Ok I dont really know the awnser to that, but mine is coming on also,I never knew there was a way to clear it how do you do it properly? and if mine or yours is "going to crap" what can happen?

RE: CEL : Crankshaft Position Sensor
I pulled a Crankshaft Speed Fluctuation CEL once and after looking at diagrams and searching my engine bay for a while I finally found the problem: the alternator belt I think was rubbing away at the wire that leads to the sensor!
So cut and replaced the damaged section of the wire and rerouted it so it wouldn't rub anymore...problem solved. Just make sure you check for the obvious first. You might have some bad wires or connections or maybe a bad sensor. |

Yeah guys the wire for the sensor probably fell out of the clip and is rubbing against the belt. I had that happen, the dealer screwed up when they changed the timing belt.

RE: CEL : Crankshaft Position Sensor
The BACK UP fuse (7.5 A) in the under-hood fuse/relay box is used to provide power for storing CEL codes in the ECU when the car is turned off. As you may know, removal of this fuse for 10 seconds is an easy way to erase CEL codes from the ECU. I suggest that you check whether this BACK UP fuse is blown. If so, the ECU would be able to store CEL codes when the car is running but the codes would be erased when the car is turned off. The BACK UP fuse also functions to store clock and radio presets when you turn off your car. Do you by chance also happen to lose clock and radio presets when you turn off your car?
I assume that the CEL code you have retrieved is 4. Pictures here and in the next post may help you troubleshoot this separate problem. [IMG]local://upfiles/25538/500FC4438CD84788B6FACADCAE6D4D32.jpg[/IMG] |

RE: CEL : Crankshaft Position Sensor
thanks!
My clock and radio retain their memory. I have yet to check the wiring because it's freakin' cold outside. Plus, it hasn't done it in a while, lol, it's stupid. |
RE: CEL : Crankshaft Position Sensor
Back to the drawing board. I missed the fact that the abnormal clearing of the code is linked to starting rather than turning off the car.
Do you happen to remember the specific CEL code you retrieved? When the CEL turns on does it remain on until you turn the car off? |
