CONDITIONS FOR SETTING THE DTC
DTC 51 will set if TPS1 and TPS2 disagree by greater than 5.96%
A short circuit code will set if the TPS1 (as shown on the diagnostic monitor) is greater than 99.02%
of the 5 Volt Power Supply 1 (approx. 4.95 volts)
A short circuit code will set if the TPS2 (as shown on the diagnostic monitor) is greater than 99.8% of
the 5 Volt Power Supply 1 (approx. 4.99 volts)
An open circuit code will set if the TPS1 (as shown on the diagnostic monitor) is less than 4% of the 5
Volt Power Supply 1 (approx. 0.2 volts)
An open circuit code will set if the TPS2 (as shown on the diagnostic monitor) is less than 4% of the 5
Volt Power Supply 1 (approx. 0.2 volts)
