Hi all, right where to start, just got my first land rover 1999 disco 2 195000km.
1. drivers door is the only door that opens with the key and the switch on the dash.
2. i have the three amigos (but ive been iformed that it could just be a wheel sensor...mmmm)
3. check engine soon light soon light was on so a OBD2 reader was ran on it today and the following codes came up p1590,p1037,p0160,p1173,p1170,p0161 & p0154, all were cleared ses light is now out just the three amigos left to deal with, i tried to search the codes but kept getting conflicting results as to what they were.padsd and brake disks are about 70% left on them
please help to idenfify the codes and the other faults many thanks

Cut and paste from RAVE.

p1590 ABS rough road signal circuit malfunction Hardware is OK, but SLABS ECU is sending an error signal

p0160 O2 sensor circuit no activity detected (bank 2, sensor 2) Rear sensor RH bank open circuit (NAS only)

P1173 Downstream fuel trim malfunction (bank 2) Front sensor aged - rear HO2S adaption too lean/too rich RH bank (NAS and EU-3 only)

P1170 Downstream fuel trim malfunction (bank 1) Front sensor aged - rear HO2S adaption too lean/too rich LH bank (NAS and EU-3 only)

P0161 O2 sensor heater circuit malfunction (bank 2, sensor 2) Rear sensor heater RH bank - short/open circuit (NAS and EU-3 only)

P0154 O2 sensor circuit no activity detected (bank 2, sensor 1) Front sensor RH bank open circuit

For the amigos, you'll need to find someone with a scanner that can read them.

 

i had a friend look at the car he said the engine looks like it has been out at some time and the codes may not have been reset? if the SES light stays off could this be a posiblity?

 

As long as it seems to run ok, I'd say waiting to see if the codes come back sounds ok.

 

thanks you very much, any clue as to the central locking i have read alot of reports but not to sure what to go with?

 

Someone who swaps a motor is not going to skip the 10 second task of clearing the codes. That's a fantasy land pipe dream.

You're going to replacing your O2 sensors - likely all of them - very soon when those codes come back on.

 

You will need to replace all 4 02 sensors for sure, 3 amigos doesn't mean you need a sensor, there are 16 possible things that will trip them, better buy that used 3 Amigo scanner that is listed here, it will be cheaper then going to a shop 2 times, once to read the codes, the second to clear them.

 

Mike is all over it.

Those errors will flash again. Give it a few miles. A reset turns them off, but a few hundred miles will turn then back on again if the issue it not addressed.


On the bright side all of your codes are fixable with not a lot of physical work.

 

be sure i didnt think that was the end of the O2 sensor issue, i was just giving my machanic friend a shot at his theory ie the fact that the engine has been put back in it not to long ago, as for the three amigos i fully understand it may not just be a sensor, i just know i have at least one to change. thanks to all for the info, i now need to address the central locking issue.......

 

When you try to lock or unlock, do you hear anything from the doors that don't work?
