INTRODUCTION
If you encounter a vehicle which has P0128 stored in memory, it may be caused by a very
slight variation in coolant temperature between the left and right cylinder bank.
The slight variations can be contributed to owner driving patterns. As an example, how long
a vehicle is permitted to warm up, heater use during cold or hot engine temperatures, etc. An
air pocket within the coolant system can also cause the code to set. A countermeasure heater
hose pipe is now available which contains an orifice, designed to regulate coolant flow past
the coolant temperature sensor.
