2 Questions on my 2004 Discovery 2 w/ 89000miles - would welcome advise as thoughts range from the inexpensive to expensive. Mechanic has replaced
4 - O2 sensors
MAF
Smoke tested
1 - Been battling the following codes after cleaning O2 connections. P0150: P0174: P1174:
b - Cleaned connectors with contact cleaner
c - See Voltage of O2 sensors. When starting car all voltages rise to .5volts. Then B1S1 and B2S2 begin to operate 'normally' swing from 0 to .9 v. B2S1 and B1S2 voltage drops slowly to 0volts over 30 seconds.
d - mechanic did a smoke test and found a leak at Intake Manifold area
2 - What is this open ended hose and what impact left like this does it have?
Am I right in position
Bank 1 Sensor 1 = US Drivers Front
Bank 1 Sensor 2 = US Drivers Rear
Bank 2 Sensor 1 = US Passengers Front
Bank 2 Sensor 2 = US Passengers Rear
Vehicle VIN: SALTL...
Vehicle Manufacturer: Rover
Vehicle Calibration ID: Not present
Current Fault Log
------------------
P0150: O2 Sensor Circuit (Bank 2 Sensor 1)
Pending Fault Log
------------------
P0174: System too Lean (Bank 2)
P1174: [BMW] Fuel Trim Adaptation Additve Bank 1 Malfunction
Historic Fault Log
------------------
ECU reports no historic faults
Other discovered fault codes
(possibly pending, current or manufacturer specific)
----------------------------------------------------
ECU reports no other fault codes logged
End of report.
