Fix the P0793 code. Intermediate shaft speed sensor. The others will go away, depending on the year of your car. Any transmission codes and some engine codes will shut down ABS and VSC systems.
Thanks u sir. Where is the intermediate shaft speed sensor located and how do I remove it
It is under the air filter box. Mounted to the transmission. Two wire plug connects to it.
A 10 or 8 mm socket removes the bolt, then twist and pull it out.
Just a note. This could be the sensor or wiring. The sensor can be checked with an ohm meter or a hertz meter. With the wiring it could be corrosion(white to greenish white coloring in the sensor and plug) or the wire is broken. Wires tend to break right behind the plug. Check with on ohm meter.
Thank you very much Randy Ohler. I removed the air filter unit and discovered that both wires were broken just behind the plug. Since the wires could not be joined, I replaced the plug with a new one that has long wires, joined the wires and that was the end of the problem.

Often caused by a loose gas cap or fouled or failed air fuel O2 sensor. Check your gas cap is fully ratcheted, Drive a day or two. If lights don't clear you will need a code reader attached to the car to diagnose.

The VSC warning light, Trac Off and check engine is probably an easy fix. If you look under the air filter/cleaner box there is probably a rubber hose that has been disconnected from a steel line. This is common if you have had the oil changed recently, the tech will check the ail filter and doesn't realize the hose has been disconnected.
SOURCE: what is PO 330 Knock
P0330 = "knock sensor no.2 circuit malfunction (bank 2)." This sensor is on the bank of cylinders which contain cylinder No.2. Either the sensor is bad or the wiring to the sensor is bad. The knock sensor detects when pre-ignition (pinging or knocking) is occurring and tells the computer. The computer then retards the ignition timing to prevent engine damage.

Randy Ohler. Thank you very much. I removed the air filter housing and discovered that both wiring of the intermediate shaft speed sensor were damaged. check engine and vsc light went off after fixing the damaged wires.
