1990 LX ACCORD SPEEDO PROBLEM
Hey folks,
I got a 1990 accord lx with automatic Speedo works when it wants, usally as car and temp warms up. Honda dealer said speed sensor is bad, at a $190.00 a pop ( wow ) I want to get some inputs. I am both mechcanic and electronic skilled . Not afraid to tear into it as I done ALL the work on this car and others in the past. Dealer or service not an option. It looks as though the sensor can be taken apart. Anybody try it ? Any recomemdations for a cheaper source ? Look forward to any replys Thanks John |

The speedo itself could be intermittent. That doesn't really make it any cheaper, but the least expense is always to replace only the defective part(s) 8^{ Bad solder connections on the speedo circuit board are still a suspect. A more affordable way to go with DIY troubleshooting would be to get a speed sensor from a wrecking yard. The pull-your-own type of yard would probably sell you one at a price you could live with for the chance of fixing the problem. Mike |

Re: 1990 LX ACCORD SPEEDO PROBLEM
Thanks mike,
What I plan on doing this weekend is using an Oscope to trace the signal comming out of the sensor. That should deffinately tell me where the problem is. Wish I had a factory manual for or least the section on as it would really help.

If the signal doesn't disappear or at least get wimpy, no point to going that direction! There has been some speculation about bad solder connections on the speedo circuit board. IIRC the instrument panel is somewhere between "a pain" and "not awful" to get out. Mike |

Re: 1990 LX ACCORD SPEEDO PROBLEM
Sounds typical of speed sensor. You can get the part online for less than
$120. 78410-SY0-003 is for 90-91 accords. 78410-SV4-003 is for 92 and up accord but will also work, and it's less than $90. One of them has a short pigtail with a connector, and the other the connector fixed to the top of the sensor. It doesn't matter so don't let that make you think you have the wrong one. <ielw@bellsouth.net> wrote in message news:yO9Td.7724$Q47.1986@bignews5.bellsouth.net... > Hey folks, > > I got a 1990 accord lx with automatic > Speedo works when it wants, usally as car and temp warms up. > Honda dealer said speed sensor is bad, at a $190.00 a pop ( wow ) > > I want to get some inputs. > I am both mechcanic and electronic skilled . > Not afraid to tear into it as I done ALL the work on this car and others > in > the past. > Dealer or service not an option. > > It looks as though the sensor can be taken apart. > Anybody try it ? > Any recomemdations for a cheaper source ? > > Look forward to any replys > Thanks > John > > |
