got a c20xe in a mk3 astra(coil pack engine)
paper clip tested the ecu and got
13 oxy sensor(dont have 1)
21 Throttle postion-high voltage
22 Throttle position-low voltage
31 crank sensor-no signal
48 battery voltage
73 Air flow sensor-low voltage
i know that the alternator is not charging fully(only 11 volts)
but the car is really holding back cutting out and just generally running rough
any1 got any ideas cheers
just remembered 31 came up cause car was not running
Alright mate i dont have anyt advice for you, but could you tell me how to paperclip test the ecu as i have the same engine and my ecu light is on? also how many flashes to each no etc. many thanks.
First of all you need to reset you ECU by taking on of one of the battery plugs for a minute then run your car for 10 minutes then take the fault codes same times one of the codes is related to another I advice you to solve your alternator problems first then start working one buy one
the crappy power supply will effect the normal opperation of all the sensors, i'd put money on an altenator sorting it buddy
gave the battery a good charge and had it on while running, all the low voltage faults are away. got an oxy sensor in which helped. but still got fault 21, now after a bit of staring at the engine ive found out that im running an early throttle body on a late engine so throttle position sensor is different if im right????
no there's only a choice of 2 buddy, and if it was wrong they'd be blowing for fun.
My engine has this throttle and tps
after a few more checks with a tps like this
on track 1 - 5volt feed, track 2 - earth and track - 3 is between 0.28 and 4.74 volts depending on what position the sensor is in. am i right in thinking thats ok, if it is i need a throttle body that this sensor fits onto later xe or let 1 i think??
that sensore isn't off an xe buddy, its off an ecotec model.
is the later xe and ecotec 1's not the same???
no there not buddy
just bought your sensor from andrew page 35 quid the other type is ecotec and totally diffrent.And if your alt is crap your car will be running on your battery so your only getting 11 volts so it will run like crap until it has 12 volts running through the electrics.
the alternator problem is fixed
