The TCC should cause no start issues, Are you in Australia? Just curious

You have done your homework. Go ahead and replace the EGR, The EGR valve position sensor is commonly part of the EGR valve. As a result, is failure may require replacement of the EGR valve. Not real expensive or difficult to to yourself
