Stock JK TechBulletin board forum regarding issues with OE (original equipment) components of the Jeep JK Wrangler (Rubicon, Sahara, Unlimited and X) such as factory suspension parts, engine, transmission, body parts, interior fixtures and the on-board computer.
2012 Jeep JKU, I have been dealing with a re-occurring code for my driver side upstream O2 sensor.
The code is: P113E, O2 sensor 2/1 slow response (High Frequency)
I have:
- Purchased a new NTK O2 sensor
- swapped both upstream sensors
- Checked for any cuts or open wires on the connector
- Used my multimeter to check for voltage, voltage is the same for all connectors including the one in question
I am stuck trying to diagnose. Any help would be greatly appreciated!
I have attached some pictures of my scanner graphs for comparison of banks.
Upstream O2 Sensor stuck on High Frequency, help
