Car Forum / Honda Cars / February 2005need obd0 help - 91 crx
anyone have experience with a code 8 condition? my crx is flashing this and will not clear. it has a brand new distributor & drives just fine. the check engine light is not on. code 8 is supposed to be for tdc/crank sensor, but are there any other conditions known to cause this? [for instance, code 16 is injectors, but is usually caused by the main relay] thanks! > anyone have experience with a code 8 condition? > > my crx is flashing this and will not clear. it has a brand new > distributor & drives just fine. the check engine light is not on. Any symptoms other than the ECU flashing the code? Try clearing the code and see if it comes back again (pull backup or backup/hazard fuse for 30 seconds). > code 8 is supposed to be for tdc/crank sensor, but are there any other > conditions known to cause this?

Well, Main Relay term 3 feeds power to the injectors, but that feed is taken before the relays themselves. I guess it must be cracked solder that causes the ECU to see a no-voltage situation at the injector pins and thus set a code 16. SignatureTeGGeR?

A question then: What would be the symptoms, if any? Stumbling? Stalling? Just the Check Engine light and nothing else? SignatureTeGGeR?

Stalling? > Just the Check Engine light and nothing else? if the motor starts, there's no symptoms. if it doesn't, it lights the check engine signal & stores code 16. i've never had a motor cut out or stumble with main relay problems once the motor's running. > i've never had a motor cut out or >stumble with main relay problems once the motor's running. I have! Sumbitch left me by the side of the road near Wapela Saskatchewan. Just quit cold after coming all the way from Calgary. Had I known then what I know now! |
