Review on Kwiksen Heated 2-Piece Air Fuel Ratio O2 Oxygen Sensor Set 1 & Set 2 (Upstream and Downstream) - 234-9041 & 234-4149 by Luckie Davidson

Revainrating 2 out of 5

Still Casting Code

Was fitted to an 05 Scion TC. After correctly resetting the CEL gauge/code, the P0031 code still comes up on startup. I've replaced both O2 sensors (since this kit comes with both) and the mass air flow sensor (I thought it messed up the readings from the first O2 sensor) and replaced the new air filter and the code is still there on the first start (no driving) . Maybe the first (before the cat) O2 sensor is defective
