How would I go about fixing my tachometer? I know I need to replace the upstream on the catalytic converter and a speed sensor also. but, where do I the speed sensor on my car and wiring for the tachometer also?

Hi,

Do you need directions for the speed sensor? If so, is it the input or output sensor or even a wheel speed sensor?

As far as the tachometer, the ignition failure sensor is used to check whether the spark ignition has occurred correctly or not and also used to tachometer drive. I attached a pic of it's location. However, first confirm there is no issue with the connection itself.

Next, before you just replace this sensor, I recommend having the computer scanned again and check for a P0320

Let me know.
