    I don't know the TD27 but I'd be surprised if Nissan didn't use a similar sensor on something else. If you've got the resistance specs for what the sensor should be, you may be able to match it to a sensor from something else that might be close enough to keep the computer happy. If the old sensor's junk, you're not gonna make it any less useful by pulling it apart to look for a broken solder joint or something.
