Looking to replace a sensor with a short lead WB, Denso, Delphi, NTK. I'm doing search's but wondered if anyone had a known part number. I have miles of wire from the AEM and ecu so don't need more on the sensor side- why are the long lead version cheaper than the short lead? I'll be ordering international from RA and want to be dead sure it going to work.
According to a Google Search: https://www.tacomaworld.com/threads/...bility.501754/
After a failed trip to my local Autozone to pick up a new Bosch LSU 4.9 sensor, I begun doing some research, which like usual led to heavier research than I initially intended on doing so. This thread is purely for informative purposes on all the different options available from the different AFR sensor manufacturers which utilize the Bosch LSU 4.9 style technology and connector.
I have been having issues with my 4.9 sensor lately and will be swapping out to a Denso because in the past I have replaced 2 4.2 style sensors, and now I will be on my 2nd 4.9 sensor, so I'm done with Bosch. If you would like to swap yours out to a different manufacturer because you are having issues, I have supplied all the different part numbers available that I am aware of which should work with your AFR gauge. Longevity of listed sensors may vary.
Denso:
- 234-5102
- 234-5116
- 234-5119
- 234-5125
- 234-5136
- 234-5137 (38.66 long)
- 234-5138
- 234-5139
NTK (made by NGK):
- 24315 (39.3" long)
- 24323 (35.5" long)
- 24324 (33.5" long)
- 24325 (15.8" long)
- 24328 (29.5" long)
- 24326 (28.5" long)
- 24329 (14.8" long)
- 24330 (21.8" long)
- 24333 (41.5" long)
AC Delco (high possibility exists that they are made by Denso):
- 213-3934
- 213-3936
Again, bear in mind, longevity will and may vary, but these are all the part numbers on record which are cross compatible with the original style Bosch LSU 4.9 style type AFR sensor/ connector. The prices vary WILDLY I found between all of the different part numbers, as does wiring length, but if you want the cheapest priced one, you will find the 234-5116 on Amazon for $75.42 right now. The one I chose for myself was the Denso 234-5137, as the wiring appears to be much shorter.
Hello, I saw that.
Have a Bosch 17025 in the Toyota running a AEM AFR gauge, have a new Bosch 17321 in hand or maybe a Denso 234-5076 on the parts pile for the ecu. The 17321 has more open sampling holes- the same Ford Focus 'turbo' version as seen on RA has the 17025 type smaller holes- do you see any issue, this is a low 6lb boost turbo DD application ecu WB mounted 6 inch away from turbo in an extended O2 bung (tip only seeing gas).
The only experience I have with the Bosch LSU 4.9 WBO2 sensor is with an AEM 30-4110 AFR meter.
