I'm pulling the following codes after a full rebuild:

P1590
P0130
P0135
P0135
P0150
P0155
P0332

Now, I HAVE combed the archives here and found that most experts recommend NOT buying O2 sensors right off the bat but, i have no idea where to start with other diagnostics, specific to my codes per se.

Any help is appreciated.

 

This is what each of those code mean;

P1590 - ABS rough road signal circuit malfunction - Hardware is OK, but SLABS ECU is sending an error signal

P0130 - O2 sensor circuit malfunction (bank 1, sensor 1) -Front sensor LH bank stoichiometric ratio outside operating band

P0135 - O2 sensor heater circuit malfunction (bank 1, sensor 1) - Front sensor heater LH bank - short/open circuit

P0150 -O2 sensor circuit malfunction (bank 2, sensor 1) -Front sensor RH bank stoichiometric ratio outside operating band

P0155 - O2 sensor heater circuit malfunction (bank 2, sensor 1) - Front sensor heater RH bank - short/open circuit

P0332 - Knock sensor 2 circuit low input (bank 2) - RH bank signal less than threshold determined from ECM model above 2200 rev/min

 

Thanks @alphamale

Turns out I've got a reasonable steady coolant leak on passenger side from head or valley gasket, directly onto passenger side 02 (and likely knock) sensor.

More to come as I get the leak fixed and new front 02s ordered from Utah.

 

Ok... think i found it

after some panic-mode moments on the head gaskets, valve cover gaskets, fears about valley gasket...

heater hose is dripping right onto valve cover in the middle, dripping back to rear of valve cover gasket and down, to the head, to the starter and cover, onto o2 sensor and exhaust...

Gonna fix here in a few and test drive tomorrow..

fingers crossed no more leaks for now.

Also, will order new o2 sensors for front (rover at 165k miles anyways) from british parts of utah in order to get the authentic Bosch 02's.

Hoping knock sensor is just the crap-*** gas i have in there from 1.5 years ago...

 

Hope that it and you get back to fully functioning V8 power.

 

See http://enginecodemaster.com

Your O2's are all shorted.
Replace the two front O2's with BOSCH new O2's from Amazon.
About $60 each.

 

Bought the front 02s - waiting on shipping now.

 

Also replaced heater hoses - no more leaks.

And did the abs modulator repair (part b) - 1590 still there....

 

1590 is a generic ABS code you need something the read land rover specific codes

 

Abs amigo v1 ordered.

More to come.

When will I ever stop dumping money into my red rover?....
