The CEL came on and the OBD II reads P1150, P1153, P1155 which points to the front AFR Sensor near the radiator.
I pulled the sensor and measured the resistance but all pins appear to be open so no doubt the heater is bad.
The car seems to run ok otherwise. Checking AVG Gas mileage on the highway, it gets up to 28 mpg but it takes about 25 minutes of hwy driving using 87 octane.
I found the Denso OEM 234-9021 part online. The cheapest price was $104 so far. I did some searching and found other sensors that claim to be replacements for this car but I'm not sure about them.
I have read posts on the forum about people having problems when substituting sensors.
Here is a link to some cheaper sensors that I was considering. Any feedback is welcome.
