B2197 Saturn Trouble Repair :
The sensors receive a 5 volt reference signal from the PCM. As pressure readings change, the sensor varies the voltage and the computer reads that to determine input. In the case of a broken wire, the sensor never sees the voltage and the computer assumes a major fault. So if you get this B2197 Saturn code, first check to make sure you're getting a good 5 volt reference signal at the sensor. |
