The charge air cooler temperature sensor (an NTC thermistor) measures the temperature of the compressed charge air at the charge air cooler, depending on the manufacturer upstream or downstream of it, and is often combined with the boost pressure sensor. The engine control module uses it for the air mass calculation, boost control, component protection and to monitor cooler efficiency. P007F occurs only on engines with two charge-air paths or two charge air coolers, such as twin-turbo V engines: the sensors for bank 1 and bank 2 deviate too far from each other. No manufacturer description naming this code was found; it follows the general rule for plausibility checks of input sensors. Possible causes are a faulty or oily sensor on one bank or a problem in only one charge-air path.

Likely causes

Sensor on one bank faulty or oil-coated
Leak or contamination in only one charge-air path
Connector fault

Symptoms

  • Check engine light on
  • Reduced power possible, especially on diesels
  • Often no noticeable symptoms
