I have been gettin a code 43 which is either a knock sensor or an esc module. Where is the esc on a speed density tpi car? I just replaced my knock sensor a few months ago.

ty!

Check up by your heater box for a single tan wire with black stripe. It has a conenctor in the middle... make sure thats plugged in. The ESC or Electronic Spark Control I believe is a thing box piece about 3x3x1" next to all your relays on the right of the master cylinder.

Maybe that's called the knock module, something like that.

Thnaks bro for the reply! However, the tan wire wil cause a code 42, not a 43.

This is what I did find on the topic and thought it woudl be good to pass along incase anyone else runs into such problems;

AEngine above 67*C does a scan indicate a value of knock retard between 4* and 20*?
= iF YES, disconnect the knock sensor with ignition ON use a DVM between harness circuit #496(GF9 at the ECM and the end of the knock sensor wire)
voltage on the wire should read between 4 & 6volts.
Does it?
If yes, check the resistance of the knock sensor to engine block. It should be between 3300 and 4500ohms.
If less than 4 volts, circuit #496 is open, or faulty ECM.
If over 6volts, see if the knock wire is too close to a spark plug wire inducing voltage. or faulty ECM.
If YES resistance is good, see if the chip is firmly seated in ECM, see if harness connector is in good condition. Replace chip.
If NO resistance is bad, faulty knock sensor

Good information Craig.

Did that come from a service manual? I'm imaging that was originialy a flow chart.

I was close, I thought it was an ESC code though. Was too lazy to break out the shop manual.
