Need to remove the upper and lower air intake manifold.  There are two knock sensors for the front and rear pistons banks.  If you plan to do this yourself it is about 1 to 2 hours.  While you are at it, there is a short coolant bypass hose sitting in the same spot, replace it.  Another problem with the knock sensor is the wire harness used to connect the two knock sensors into one connection sometimes wears out and contacts the metal on the engine causing false signals to the ECM, so replace this cable also.
Just did this last summer on my 99 ES300.  Pretty easy.

You seem to be experiencing a shift lock solenoid problem inside the transmission. Possible causes are bad solenoid where you have to test the solenoid any way. Remove the trans pan and you should see the solenoid with a red wire attached. This sometimes gets pinched against the bracket inside the trans and grounds out. It could also be the wiring to the ECM or replacement ECM with updated one. Check production date, VIN break point and replace ECM if it is not the latest P/N of 89661-08061 with Denso P/N TN175200-7491.

SIMPLY FOLLOW THE WIRES FROM YOUR DISTRIBUTOR CAP OR COIL

This code means there is a malfunction with your SL Solenoid (Automatic transmission torque converter lockup). This could mean that the solenoid is bad, faulty wiring or bad engine control unit.

You must remove the rear seat back and package tray to access the bolts at the top of the strut assembly. The rest is done with the vehicle in the raised position. You will need a jack for all systems and may need some special service tools if you have the electronic modulated suspension.
