You will still be able to drive it, but some of the functions (in my case my TPS sensor was not functioning correctly as a result) will not be working properly.
If this was just something I experienced in a freak accident, it still would not work properly since your timing would be at around 5 degrees like mine was for so long. Log your car like that next time and see if you have similar timing. |
Gotcha. So to clarify the post below, you cut pin #71 and grounded out the ECU side. You then spliced the sensor side to a different pin on the ECU? Do you happen to remember what the pin # was? From the looks of things, I'm guessing it was pin #51: Ignition Switch_ST.

Without the p/n position wire going into this input, the car will have very erratic timing when you shift into drive. I learned this the hard way, and it took me weeks to figure out the reason behind it.
