i dont know why my car is doing this but it must not like me. When i put my car in reverse the check engine light comes on and i give it the gas it dies and throws a code 6 which is coolant temp. sensor i have no idea where it located. Also the light in my ecu stayed on and did not go off until i turned my car off the first time it happened. It throw the code 6 when i started it back up and put in reverse again. HELP PLEASE. It doesn't throw any codes until you put in reverse....wierd.....

 

there is a lorge blake tub that comes off the radiator. it has box on it. not intirely sure where its located on that engine but it should be on top. the black box is your sensor. tip: might be cheaper to buy new engine. sorry man. the part has to come from a dealer i think. good luck

 

the only black box in my car is the vacuum box that is on the firewall. It doesn't throw any codes when you are going into first or in neutral. I am not sure what is wrong. HELP PLEASE.

 

check your wiring, my codes were wiring related
