What does trouble code 43 on a GM car mean?
What does trouble code 43 on a GM car mean?
Trouble Code 43 indicates that there may be a malfunction in the Electronic Spark Control (ESC) circuit. ESC is used to sense spark knock (pinging) and GM Code 43 Electronic Spark Control Fault

What does trouble code 43 on an ESC mean?
Trouble Code 43 indicates that there may be a malfunction in the Electronic Spark Control (ESC) circuit. ESC is used to sense spark knock (pinging) and retard the timing to eliminate it.
What does code 43 mean on a GM engine?
Trouble Code 43 indicates that there may be a malfunction in the Electronic Spark Control (ESC)circuit. ESC is used to sense spark knock (pinging) and retard the timing to eliminate it. A knock sensor (located at the rear of the engine block) sends signals to an ESC module which then signals the ECM that knocking is being detected.

What causes a GM engine to set code 42?
When the engine speed exceeds 400 RPM, the ECM sends a BYPASS signal to the ignition module which switches the timing to ECM control. The ECM calculates what the timing should be then “tells” the ignition module via the EST circuit. An open or ground in the EST circuit will stall the engine and set a Code 42.
What happens when you set a code 42?
The ECM calculates what the timing should be then “tells” the ignition module via the EST circuit. An open or ground in the EST circuit will stall the engine and set a Code 42. The engine can be re-started but it will run on ignition module timing. The conditions for setting code 42 are:

What does trouble code 42 mean on spark timing?
Trouble Code 42 indicates that there may be a malfunction in the Electronic Spark Timing (EST) system.
How does DTC 43 work on a GM Truck?
The DTC 43 circuit consists of a knock sensor with one wire that goes directly to the PCM. There are two DTC 43 checks performed by the PCM. One check consists of monitoring CKT 496 for a voltage that is more than 4.5 volts and less than .64 volt. If voltage is either too high or too low, for 10 or more seconds, DTC 43 will set.
What’s the diagnostic code for a s 10 engine?
F for at least 4 seconds after the engine had been running for 2 seconds. 16 – System voltage high – Charging system voltage was either below 9 volts or above 17 volts for 10 seconds.
Where is the knock sensor on a GM car?
A knock sensor (located at the rear of the engine block) sends signals to an ESC module which then signals the ECM that knocking is being detected. The ECM will retard the timing by as much as 20 degrees in 1 degree increments.
