2002 Chrysler Intrepid 3.5L Frequently Reports P0152, P0141, P0139 After B1 S1 O2 Sensor Replacement

Model: 2002 Intrepid Fault Code: P0139 Posted: 2016-04-07 18:55

I recently replaced the B1 S1 oxygen sensor in my 2002 Chrysler Intrepid with a Bosch 13399 unit. Since then, the car has started displaying multiple trouble codes: P0152 (B1 S2), P0141 (B1 S2), and P0139 (B2 S1). These codes are related to oxygen sensors in Bank 1 and Bank 2. The engine now runs unevenly, with a loud idle that occurs randomly—about once per day—and feels like it's struggling under load. I'm not an experienced technician; I only have two years of high school-level automotive training. After researching online, I was told to simply remove and reseat the sensors as a simple fix. However, given that these codes are recurring and the symptoms persist, I'm wondering if this is actually a sensor issue or something more serious. I’ve already replaced B1 S1, but I’m considering replacing the remaining sensors (B2 S1 and B2 S2) proactively—especially since B2 S2 has no current issues. However, I’m concerned about internal shorts in the sensors or wiring harnesses, which are listed as possible root causes. Could these codes be due to faulty sensors, a wiring issue, or something else entirely? What would you recommend for someone with limited auto repair experience—should I attempt DIY fixes, or take it to a professional shop or Mopar at the Rock?

Check the official trouble code explanations on this forum. While faulty oxygen sensors are common, these codes can also result from internal shorts in the sensor itself or wiring harnesses. Before replacing any new sensors, it's important to identify whether the issue lies with the sensor or elsewhere. What trouble codes did you see before installing the B1 S1 sensor? Is Bank 1 (the side closest to the firewall) correctly identified?

I don’t remember the original codes—my old records are in my uniform’s laundry pile. The forum lists possible causes such as exhaust system leaks or internal sensor shorts. One suggested fix is lifting the vehicle and inspecting the entire exhaust system for damage, but I don’t have access to that equipment. Given that, should I go to a professional shop, or just replace all three sensors? Or would it be better to visit Mopar at the Rock and let them diagnose and repair it? According to official solutions under P0141 (B1 S2), possible fixes include: • Replacing the oxygen sensor (internal open or short faults cannot be repaired) • Repairing any short, open circuit, or high resistance in wiring harnesses or connectors These are the only listed remedies for that code.

I also have a serious issue with my car’s door. When I step out of the vehicle, I get strong electric shocks—sometimes severe enough to make my hand go numb. On one occasion, it shocked my phone while I had it in my hand, causing the screen to shatter and lose its protector. My seat is fully electric (not heated), which makes me wonder if there’s a grounding or electrical short somewhere. I’ve already inspected the wiring under the seat and found no visible damage—could this be related to an internal short or poor grounding in the vehicle's electrical system?

For someone with limited experience, it’s best to find a reputable auto repair shop that offers transparent diagnostics and stands behind their work. DIY fixes may resolve symptoms temporarily but could miss underlying issues. A professional diagnosis can help determine whether sensor replacement or wiring repairs are needed.
