hi guys, i got a opcom vuaxhall lead and diagnostic software for my vauxhall astra 1.8 sri 2003, il tell you my cars symtoms and then write codes up
when i start my car from cold the tick over is all over, nearly cutting out and sometimes revs up to 1500rpm. if i try to press the accelerator it tried to cut out, when the car gets abit warming when on idle its still all over the place but i can press accelerator fine, then when i drive the car its kanagrooing and wont go over 50mph but sometimes like earlier tonight i **** get above 20 mph,
so i read the errors codes which will of been stored up for abit and got the following
Total number of fault codes: 7
P0170 - Lean Exhaust
(02) - Not present
P1555 - Throttle Position Sensor (TPS) Load Signal not Plausible with Engine Load
(00) - Not present
P0135 - O2 Sensor Heater Circuit Open (Bank 1 Sensor 1)
(04) - Not present
P0110 - Intake Air Temperature Circuit High Input
(01) - Not present
P0100 - Mass Or Volume Air Flow Circuit Low Input
(02) - Not present
P1525 - Limp Home Position Error
(00) - Not present
P1550 - Electronic Throttle Control Engine Stop
(08) - Not present
after reading these thats when i went for the drive where i couldnt get over 20mph after about half a mile of drive, when i got back i read codes again and got the following
Total number of fault codes: 9
P0170 - Lean Exhaust
(02) - Not present
P1555 - Throttle Position Sensor (TPS) Load Signal not Plausible with Engine Load
(00) - Not present
P0135 - O2 Sensor Heater Circuit Open (Bank 1 Sensor 1)
(04) - Not present
P0110 - Intake Air Temperature Circuit High Input
(01) - Not present
P0100 - Mass Or Volume Air Flow Circuit Low Input
(02) - Not present
P1525 - Limp Home Position Error
(00) - Not present
P1550 - Electronic Throttle Control Engine Stop
(08) - Not present
P0302 - Cylinder 2 Misfire Detected
(01) - Not present
P0301 - <Unknown DTC>
(04) - Not present
i then reset the codes and went round the block and seemed ok, went for abit longer drive and the symptoms came back this time it wasnt the engine management light on it was the little car with a spanner light, so read the codes
P1555 - Throttle Position Sensor (TPS) Load Signal not Plausible with Engine Load
(00) - Not present
then after 10 minutes of idleing and reving up etc i read codes one more time and got the same code p1555
so not sure whats happening to my car and wondered if anyone on here could help ?
read on another forunm it might be a good idem to use my opcom software to reset the ecu, not just clear fault codes but theres a button to reset ecu but im not sure if thats ok to do,
cam amyomen help with this problem ? thanks
