So, replace the sensor to solve the code P0038 on your Jeep vehicle. On average, it will cost between $150 and $470 to replace a bad oxygen sensor bank 1 sensor 2. The labor cost can be between $100 and $130, while a new oxygen sensor can cost around $20 to $298. 5. Checking the ECM:
We bought this about two weeks ago. 05 Laredo, 46,000 miles, meticulous service records. I am getting an intermittent, like every couple of days, P0300 code - random cylinder misfire. It had plugs at 35,000 miles. I haven't checked them but that shouldn't be a problem unless they put the wrong plugs in (platinum instead of copper).
Having some issues with my recently purchased Grand Cherokee, autozone printed out my codes for me which are P0300 multiple cylinder misfire U0401-00 implausible data from ecm/pcm U0403-00 implausible data from transfer case 13. Going out on a limb here but on the Liberty's and on the Liberty forums, the 3.7 V6 has a problem of breaking valve springs, weak valve springs, etc. on valve springs. One of your Intake valve springs could be broken or worn so bad that the Intake valve isn't closing properly and could be throwing the miss fire code. Of course that's a big if. Jan 9, 2019. #1. I have a 2000 TJ, 4.0L, 5spd with the check engine light on. Sometimes, it will start blinking for a short time then return to solid again. Here are the codes I'm throwing: P0205. P0300. P0303. P0305.
