so i coverted my rex to obd1 a while ago n i got some codes n i jus got the 2 wires added to my jumper harness so i can check my codes on my dash like eg's....i get the code for 02 sensor n IAT i think.....is it because i have to rewire those sensors to obd1? if so are there any other sensors that need to be rewired to obd1?....im runing an mpfi dx n i coverted to obd1 using a jumper harness, p06 ecu, n obd1 dx dizzy....

 

bump..

 

anyone?

 

Iat... I bet you used the tandem valve plug, in the iat location. Make sure you have a red/yel and green/wht in the iat location

 

nevermind the codes are for 02 sensor n map sensor...do i have to rewire my 02 sensor? wat about the map sensor?

 

yes you need to wire for a four wire o2 sensor

 

wat about the map sensor? could jus be a bad map sensor?

 

Yea my buddies car just today threw a code for a bad map sensor... Cant hurt to try a new one out, If your sure your wirings good to the sensor
