Hello Toyota friends, after reading & deleting the error P0155, defective Lambda probe heater probe 1 (sensor 1) of Lambda probe of the 2nd cylinder group (bank 2) of my Toyota Avensis 2.0 VVT-I 16 V, 150 hp again lit the yellow engine control lamp the next day. Since then I have been driving for 8 months without deleting the lamp and without increased fuel consumption. As soon the AU is on, I fear still too high values with refusal of the AU plaque. Is there any cheaper probes for my Toyota at BOSCH or elsewhere and how about the exact name (connection right/left, serial number, etc.)? Thanks for every hint. MfG Hechti.
