P0128

Fix code P0128 – Temp Gauge Cold but cooling fans on

Shops are noticing a common problem in 2000-05 Chevrolet Impala and Monte Carlo 3.4L, 3.8L engines where the temperature gauge stays on COLD, but the cooling fans are on. In addition, the CHECK ENGINE light is on and code P0128 is in memory.

This condition is most often caused by a bad thermostat. So that’s your starting point to fix this problem. Replace the T-stat, clear the code, and restest by driving.
