So far so good
I recently bought a 1997 Tacoma with 78k miles on it. I love it, men want it and are surprised it’s a woman’s truck lol. I had a p0402 code. Replaced the Egr modulator and the light came back on a few days later. Pulled the valve (prior owner replaced a couple years ago) and it barely had carbon but cleaned it anyway and the light came back on a few days later. Did some research a saw this part replacement could resolve the issue. This part was put on over a week now and so far so good. The light has not came back on 🤞🏻

Fixed p0402 error code on my 2000 Tacoma
I recently encountered a rough idle and a P0402 code on my car, indicating a potential issue with the EGR valve, cleanliness, or sensor. Before delving into the more labor-intensive task of replacing the EGR valve, I opted to swap out the DPFE sensor first. To my relief, the new sensor was a perfect match to the OEM part and exhibited excellent quality. A word of advice for those attempting this fix: don’t forget to retain your original mount and transfer it to the new sensor. Neglecting this step could lead to improper grounding and trigger additional error codes. In summary, this DPFE sensor proved to be an outstanding replacement. It resolved the error code, allowing me to proceed with the smog check. Highly recommended for a hassle-free fix!

Perfect fit for my 04 Tacoma
The part was a perfect fit, the engine design by Toyota was the challenge. It would really help to have smaller hands to do this job quicker. Solved the check engine light right away.

Perfect match to OEM
Same brand as OEM, just doesn’t have TOYOTA printed on it. Also cost is way less. Installed on my 2001 Tacoma 2.7. Located under the intake manifold, not an easy task. Took me 1 1/2 hours, professional could probably do it in a quarter of that time. My Blue Driver diagnostic dongle was correct, this was the defective part. It’s been months since installation without another CHECK ENGINE light. Super satisfied. If you’re not very mechanically inclined, I would recommend professional installation.
