This week, our favorite fix is for a 2016 Chevrolet Silverado that will not start, has no crank and the cluster goes black.
The Vehicle:
2016 Chevrolet Silverado
The Problem:
The vehicle will not start, has no crank function, and the cluster goes black while in the crank position. The DTC’s are as follows: P00C7, P0106, P0192, P0193, P0341, P0641, P2227, P2228, and P2230.
The Diagnosis:
By using the scan tool, I looked at the 5-volt reference 1 reading. This is the 5-volt circuit that is common to all of the sensor faults listed. If it’s reading low or 0 volts, unplug the sensors one at a time called out by faults. I started with the fuel-tank, fuel-line, and fuel-rail pressure sensors, the multi-function intake air sensor, and the a/c pressure sensor. Then I watched the voltage on the scan tool as the sensors were unplugged. Once the voltage goes up to 5-volts, the faulty sensor is successfully identified.
The Solution:
Use the scan tool to find the faulty a/c pressure sensor.
