Do you have any aftermarket parts on your car? I've gotten the P2241 code both before I had PPE headers with OE O2 sensors AND AFTER PPE headers (with O2 sims w/ extenders) with new Denso O2 sensors. Very random when it appears; but it doesn't affect the way the car acts. Plus, I can just turn the car off and back on to remove the CEL from the cluster.
yes I changed sensor upstream left, aftermarket parts, China made
do you know this parts munber for this sensor B2S1 upstream left
the one I changed is Denso 89467 - 03390 made in China
thank.
