Re: help with codes
I'm assuming the car is question is your '93 SHO since you didn't state what car.
The code 217 is probably the cause for the 172. Check/replace your coil and you'll probably fix those two codes. As for the 117, you need to check the sensor and the associated wiring. If you have a stash of resistors handy, you could bypass the sensor to see if the code goes away. If it does, then the sensor is likely the problem. If it does not, then your wiring probably has an issue. -Rod
