On the April 18, 2009 cartalk show a woman called in about a 2001 Nissan Altima which was spiking overheat and would not go above 2.2K on the tach during a long trip. When she would press the accelerator to go faster she would hear a growling sound. Later it was determined that the temp gauge was way up.
I was wondering if Nissan uses the limp home mode of cutting fuel injection to cylinders to keep the heat flow managable. Cadillac used to have this feature in its PCMs so I was wondering if Nissan might have included this feature in its PCMs.
Just curious – searching for knowledge.
I don’t know the answer to this but I’ll bet your local Nissan dealer does.
The engine not exceeding 2.2K could be an ECM issue. Gotta love those KA24DE truck engines
