Well the LS gets code 43 now, the last 2 days. Both times it comes on after reaching operating temperature and it came on when under acceleration. Car runs fine, until the code came on. Nothing odd at all....car has driven a few times between both instances with it not coming on at all.

Checked the manuals steps and faulty ECM, bad knock sensor, ESC module or connection/ground are possible culprits.

Any tips, or usual suspects? Ill check the connections/how it looks tonight, but I think it should be fine. The sensor is the original one in the LG4, but worked just fine for the TPI....maybe its just time for a new one.

 

Hey Paul.

Code 43;

• ESC control failure
• TPS out of adjustment
• Knock sensor signal

So I would try setting the TPS first as it costs nothing. Look here for instructions https://www.thirdgen.org/newdesign/tech/tpimod2.shtml

If that dosen't work check the Knock sensor to ensure the wire is connected, and it condition. Trace it the ESC module. If all the wires look good, the ESC module may have fried. HTH's?
