98 Dodge Ram 1500 P0132 Fault: Causes and Solutions with O2 Sensor Replacement
I recently purchased a 1998 Dodge Ram 1500 4x2 with a 5-speed manual transmission. When I took it for a check engine diagnosis, the system showed codes P0138 and P0135. After troubleshooting, I resolved those by replacing a downstream O2 sensor fuse. Now, a new code has appeared: P0132. I suspect this is due to installing a Bosch universal O2 sensor instead of the original equipment manufacturer (OEM) part. Could this be causing the issue? Any insights or recommendations would be greatly appreciated.
Yes, that's likely the root cause — using a non-OEM sensor like Bosch can trigger P0132. I recommend visiting your dealer to replace it with the correct OEM part. Good luck, and let us know how it turns out!
