After cleaning Mac sensor it seemed to run fine though every couple of days engine light is displayed and reverts back to limp mode. I have x 2 fault codes of PO191 and PO652. Was hoping that there was a rethink process to rectify. Key on off sect. Any help appreciated Thanks
P0191 fuel rail pressure sensor circit
p0652 sensor1 low supply voltage
there first one is possibly a loose connection.
The second is the code for bad gas pedal sensor
replace sensor for gas pedal /check connector at the fuel pressure regulator
i have fault codesU1101&0758 BUT I SEEM to have the same problems ROD from above question

My girlfriends car has just started with the same problem, a limp home from the garage, a sleep over night and als well next day, for a while... I spoke to Mitsubishi and they have told me the TPS (throttle positioning sensor) is on the accelorator pedle assembly. There PN for this is MN125791 and its circa £88 + VAT. After exhausting all other options I may attempt this replacement and will advise the results.
