MAP Sensor
Posted: Wed Jul 18, 2018 8:03 am
Hi Guys
Hope fully one of you can help me out. I am building a 206 rally car, the engine is a standard 206/C2 1.6 16V TU5JP4 with standard plastic in take and a 206 gti cable throttle body. I have used all the original sensors.
The engine is running ok (with the MAP sensor disconnected and set at 100 kpa)
The sensor is Bosch no 0261 230 043 which has 4 pin connector and has a build in air temp sensor (which i am not using)
the problem is that sensor is scaled 20 kpa to 115 kps on approx 200 mV to 4600mV
(100 kpa should be around 4000 mV) but at around 100 kpa i am getting an out put of 650 mV
The pins are wired 1 to ECU Ground, 2 not used, 3 5V feed from ECU and 4 Signal out put to ECU.
I have tried 3 different sensors ( one i dorrowed from my mates road going C2 VTS)
There is something wrong somewhere but i cant find it so if somebody could be of assistance that would be appreciated.
Thanks
