The Check Engine light came on recently. At the same time, I noticed some performance issues, particularly when accelerating from about 25 MPH; the car would hesitate before taking off.
I had the folk at my garage pull the error codes and we discovered 14 of them.
P1590 -- Mfg Specific Code
P0134 -- O2 Circuit, No Activity, Bank 1, Sensor 1
P0154 -- O2 Circuit, No Activity, Bank 2, Sensor 1
P0448 -- Evap Emission Sys, Vent Circuit Short
P0445 -- Evap Emission Sys, Purge Valve Circuit Short
P0102 -- MAF or VAF Circuit Low Input
P1884 -- Mfg Specific Code
P0340 -- Cam Shaft Position 'A' B1 circuit malfunction
P0135 -- O2 Sensor, Heater Circuit Malfunction, bank 1, sensor 1
P0155 -- O2 Sensor, Heater Circuit Malfunction, bank 2, sensor 1
P0141 -- O2 Sensor, Heater Circuit Malfunction, bank 1, sensor 2
P0161 -- O2 Sensor, Heater Circuit Malfunction, bank 2, sensor 2
P0140 -- O2 check, no activity, bank 1, sensor 2
P0160 -- O2 check, no activity, bank 2, sensor 2
We are speculating that it is the MAF sensor & the O2 sensors but the camshaft sensor and Evap Emission stuff has me hesitating.
Mileage is horrible and the exhaust smells very rich.
Vehicle: 2001 Disco II
189,000 miles
Head was rebuilt at 130,000
Any and all help/suggestions are welcome!
Thanks,
Jim
