ERROR CODES - 4/28/2008 9:30:37 AM

Status: offline I took my 2001 Disco II w 109k on the odometer to have the TEXAS inspection done a week ago . The OBDII came back with two error codes that failed the inspection PO133 and PO153. I had a shop I trust replace the two front bank sensors and reset the codes. I drove my Truck home and the next morning discovered the Service Engine Light was on again. I took my Truck to Auto Zone and they we kind enough to read me new error codes of PO155, PO135, PO134 and P1590.

Any suggestions on what these codes are ? I have looked them up online
IE PO135 ( this is not a specific land rover code)
This code refers to the front oxygen sensor on Bank 1. The heated circuit in the oxygen sensor decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it. The ECM tracks how long it takes for the oxygen sensor to begin switching. It the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0135.

Status: offline 135 is a rover code, 02 heater circuit malfunction, bank 1 sensor 1
1590 is for your ABS and will need to be scanned with a much better scanner to find and correct it.
134, no activity to from bank 1 sensor 1
155 is a heater circuit malfunction bank 2 sensor 1

Start looking at the 02 wiring harness.
By the way, you need all 4 02's replaced based on your mileage.

Status: offline That 1590 code won't clear with a hand scanner, it will have to be done with a lap top type scanner that can access your ABS codes.
Does your ABS still pulsate when you brake hard?
