Whoosierdad Posted October 30, 2020 Report Share Posted October 30, 2020 I replaced both upstream o2 sensors on my son's 2014 Dodge Journey after retrieving a code saying that bank1 upstream o2 sensor is bad. After replacing those, I now get P0219A and P0219B codes. i've checked all of the obvious conditions for the codes, but just wondering if anyone else has experienced this issue and what they did to resolve it. Thank you. Quote Link to comment Share on other sites More sharing options...
5rebel9 Posted October 30, 2020 Report Share Posted October 30, 2020 Air/fuel ratio imbalance ,,,probably running rich. How many miles on it and what maint has been done recently(spark plugs,coils) leaking (dirty) injectors and such. Did you clear codes and drive it or did the P0219a/b show right away? Check the map sensor connection and possible bad MAP sensor. Quote Link to comment Share on other sites More sharing options...
Whoosierdad Posted October 31, 2020 Author Report Share Posted October 31, 2020 It has about 180k miles on it. i read somewhere else about the o2 sensors that i used to replace the old ones not being OEM. It said that they went back to OEM sensors and the codes went away. I think i will try this today and see. We did a tuneup about 40k miles ago. During that tuneup, we replaced all plugs and boots. It was running great, even when the o2 sensor code came up. I thought we were being proactive with replacing both upstream sensors, instead of just the one that was faulted. Thank you for your response. 2late4u 1 Quote Link to comment Share on other sites More sharing options...
5rebel9 Posted October 31, 2020 Report Share Posted October 31, 2020 Thanks for the further info, it helps complete the "picture" Yes these cars are particular about who builds these type parts, and going with OE or mfg. imprint on the originals is best. At the miles you posted, I'd tend to believe just a worn out part, and yes about replacing both. But keep in mind that there can be other causes for code setting that points to a sensor, and why I offered a few things in my response to you. GOOD LUCK, and please report back any outcomes to the challenge . Quote Link to comment Share on other sites More sharing options...
Whoosierdad Posted November 1, 2020 Author Report Share Posted November 1, 2020 UPDATE: I replaced the new Bosch o2 Sensors with NTK o2 sensors. Codes reset, and have not come back. No more "Check Engine Light." Car is running fine. Oreilly's did give me a refund on the Bosch o2 sensors. I don't think they were too thrilled about it, but I explained the entire situation so they had no argument. LOL Thank you again! 5rebel9 and 2late4u 2 Quote Link to comment Share on other sites More sharing options...

John/Horace Posted November 3, 2020 Report Share Posted November 3, 2020 I have also posted here about NTK sensors working well with Journey. Along with a pic of the oem and NTK sensors side by side. They are identical right down to stamping marks on sheet metal housing, markings on plug. Hyundai also uses NTK as their oem o2 sensors, I had 200k miles on these sensors before. Journey also uses Denso alternators; another much above ave parts company IMO. 2late4u 1 Quote Link to comment Share on other sites More sharing options...
