2003 Chrysler T&C 3.3L Engine Throwing P0141 Code at Only 9,000 Miles
I own a 2003 Chrysler T&C with only 9,000 miles on the odometer. The vehicle has been sitting idle for an extended period and was previously used very little by its former owner. The van currently shows a persistent OBD-II diagnostic code P0141, which is related to the oxygen sensor heater circuit in Bank 2, Sensor 1 (after-purge). This code did not appear before but has now surfaced after previous occurrences of P0139 and P0140 — both of which were resolved. My question: Why would a vehicle with minimal driving history trigger this code? And why can't the P0140/P0141 codes be cleared once they appear? What is the severity level of P0141, and what are typical repair costs for fixing it? Any insights or technical explanations from experienced users would be greatly appreciated. Thanks in advance!
If you previously had both P0139 and P0140 codes, and now the vehicle is showing P0141, then the issue was not fully resolved. These codes are closely related — they all pertain to oxygen sensor heater circuits in the exhaust system. You should return to the repair shop that fixed the earlier issues and request a full diagnosis or refund if necessary. If the code returns immediately after clearing, it likely indicates an open circuit or wiring fault.
