Sensors used in Open Loop 1999
Anyone know what senors are used during the OPEN LOOP phase of engine operation. Mine is not running good during the open loop, once it goes to closed loop everything is great.
Thanks,

It ignores the o2 sensor. I'm pretty sure in order to richen the air/fuel mixture, it uses the IAT, MAF, & TPS. The CTS is used to skip/end the Open Loop phase if the engine is already warm or if the Open Loop doesn't time out first.
