P2196: O2 Sensor Signal Biased/Stuck Rich Bank 1 Sensor 1

“A stuck CPV is leading to excessive vacuum in the fuel vapor system, causing the plastic fuel tank to deform, resulting in an inaccurate or erratic fuel gauge indication, inaccurate distance to empty (DTE), and/or other drivability concerns. The vehicle also is exhibiting an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P0420, P1450, P0443, P0452, P0456, P0460 and/or P2196”2016 Ford Focus · Jul 2021

“The car has had problems with stalling for several months, when in motion both at low speeds and up to 40 mph, as well as at idle. Each time the check engine light has illuminated. It has given codes p2196 and p1450. We took it to the dealer for diagnosis, and they said it needs the fuel vapor canister purge valve replaced. I noticed that ford issued a safety recall for the focus, 18s32, for a faulty vapor canister purge valve, and have found much evidence on the internet that this is a common problem across ford product lines. This is not covered under either the emissions or the powertrain warranty. *tr”2016 Ford Edge · Apr 2020 · 39,500 mi

“2.0l ecoboost, 40,000 miles, fwd, engine tries to stall when coming to stop at traffic light, rough idle, makes groaning or thrumming sound similar to helicopter. No power when using accelerator, engine off then on clears issue. Read p2196 code, cleaned maf sensor, but stalling returned. Random, not regular failure, so not able to recreate on demand. No fault code logged most recent incident. Has occurred 4 times over last month”2016 Ford Edge · Mar 2020 · 39,630 mi

“The engine light is on in my car. I took it to a repair shop and they said it had the codes of p2196 and p2198 a h02s heated oxygen sensor is malfuntioning. When the rep pulled up the codes he informed me they had thousands of my same vehicle with the same problem. I contacted ford warranty and they said it was not covered. This is horrible for ford to know this is a defect on their vehicle and not be responsible for fixing it. So I would like to launch this formal complaint. I will never buy another ford vehicle again. The aip has gone out in my vehicle and I have had other issues that the ford warranty has said did not apply. The vehicle was in motion when the light came on.”2013 Ford Edge · Jan 2020 · 90,000 mi

“Check engine light has come on several times with codes p241a and p2196. I have replaced the o2 sensor 3 times within one year. I have been told that this is a common issue and have been told that it is the wring harness.”2011 Dodge Ram 2500 · Jan 2017 · 42,000 mi

“Took our 2014 passat tdi in for a check engine light on 7/18/16 after testing a fault code of p2196 indicated an 02 sensor was faulty. Negotiated to $300 to repair/replace unit. Picked up vehicle on 7/21/16 after repair was made. On 8/3/16 check engine light again came on. Returned to dealer and they indicate that the adblue heater element was faulty. Recommend replacing at a cost of close to $1,000.00. Since this is part of the emissions issue we feel that this should be covered under any and all warranty. The vehicle has 48,875 miles on it and is only 2 1/2 years old.”2014 Volkswagen Passat · Aug 2016 · 49,292 mi
