My engine light came on a couple of weeks ago and I went down to autozone an they put the engine light machine on for me to see what it was. Their machine came out with troubleshooting code P1188 & P1189.. So I went on the net a did a search to see what that meant and I found out that it has something to do with the "Fuel Tempature Sensor B Circuit High Input" for the P1188 code. As for the P1189 it said "Fuel Tempature Sensor B Circuit Intermittet".
Does Anyone know exactly what that means and what needs to be changed here in this scenario?
Your car is rich or lean you need to look at additive and multiplicative values and determine your next course of testing.
I posted some DIY smoke machines testing somewhere. You can also use carb clean but it not accurate but it may find the leak
