Electrical problem
1997 Honda Accord 6 cyl Front Wheel Drive Automatic

I went to AutoZone for a check engine light on. They put the analyzer on it and read code P0725. the definition for code said:
aaTcc does not engaged.
Probable cause:
aa1. - Check ignition system for faults.
Autozone told me it probably was Speed Sensor as the tach was going all over the place and sometiems just indicating 0 rpm. Researching this on web it seems that people that have P0725 have the Speedometer going wacky. Wondering if this is the sameor could something else be causing this ?

DTC P0725: Accord V6

On 1995-97 Accord V6s, when you troubleshoot a fluctuating tachometer OR A/T DTC P0725 (lock-up clutch does not engage), keep in mind the cause could be a faulty resistor in the ignition coil. The transmission control module (TCM) provides electrical pulses through this resistor to drive the tachometer. Although a faulty resistor doesn?t affect the coil's ignition functions, you'll still need to replace the ignition coil to fix a fluctuating tachometer OR A/T DTC P0725 the coil resistor isn't available separately. Order P/N 30520-P0G-A02, for the ignition coil.
