Four cylinder front wheel drive manual 197,000 miles.

My speedometer works intermittently at best. It is not working three quarters of the time. My odometer does not register whether the speedometer is working or not. Could this be a vehicle speed sensor problem? And if so where is it located on the vehicle? Thanks

Hello, Thanks for the information. I have attached the test procedures for the speed sensor: 1. Check for blown 10-amp gauges fuse in dash fuse block. Disconnect 3-pin connector from speed sensor, located on right side of engine. 2. Use an ohmmeter to check continuity between black wire terminal and ground. If continuity exists, go to next step. If continuity does not exist, check black wire for an open circuit. Also, check for poor ground. 3. Turn ignition on. Use a voltmeter to check voltage between yellow wire terminal and ground. If battery voltage is present, go to next step. If battery voltage is not present, check yellow wire for an open circuit. 4. With ignition on, check voltage between white/blue wire (orange wire on Accord) terminal and ground. If voltage is about five volts, go to next step. If voltage is not about five volts, check white/blue wire (orange wire on Accord) for an open circuit. 5. If continuity and voltage checks are okay, but speedometer/odometer/trim meter does not operate properly, replace speed sensor. It sounds like it may be the sensor, but I would still do the check. The sensor is on top of the trans-axle.

Hello, Also, it looks like you may have some recalls on your vehicle. The dealer may fix these for free. Please contact the dealer service department, give them the VIN number of your car and have them check on these to see if they apply to you.
