Tech Tip: Failed TPS and Clear-Flood

If you encounter a no-start with good spark and proper fuel pressure, check the throttle position sensor voltage. If TPS voltage is higher than 3.5 volts, some computers will enter clear-flood mode.

If you encounter a no-start with good spark and proper fuel pressure, check the throttle position sensor voltage. If TPS voltage is higher than 3.5 volts, some computers will enter clear-flood mode. This is often the result of TPS damage caused when carburetor spray cleaner enters the sensor through the throttle shaft during throttle bore cleaning.
