My daughter finally got time to take the 03 Sonata with 59489 miles on it to the dealer. I posted that I had found the P0160 code stored after the CEL had gone out. Here's what the tech wrote on the receipt.
FOUND CODES P0056, AND P0160, FOUND THE B2/S2 02 SENSOR TO BE OPEN CIRCUIT OP CODES -- 39213ROA..0.40 // -- 39213RPO--..0.30 N69 // C15 REPLACED THE B2/S2 02 SENSOR
I was surprised to see that it had picked up another code, but pleased that he replaced the sensor. What puzzles me tho is that the CEL never came back on. Wouldn't you think that anything that serious would keep the CEL on? I just checked for codes on a lark, not expecting to find anything.. It could have very easily been ignored when it went out and not have come back on until later when it was out of warranty. The tech obliviously cleared out the codes and even tho it had been driven over a hundred miles the HO2S monitor was still not ready, all the others had completed. I took it out and drove it over 20 miles at hwy speed, but it still did not complete. Hopefully the monitor will complete and the light/code will not come back. I told here that if it does, to drive straight to the dealer even if it over
60000 miles.
