When checked with scan tool it said P0037 which is down stream oxygen sensor heater circuit low left cylinder bank. Can you tell me what the problem is? I changed Up and downstream sensors and there was no change.

If you mean by no change the engine light didn't turn off, you will need to clear the code with a scanner that is equipped to do so. Most newer vehicles have to have codes cleared that way.
