P1071 Error Code
Hey guys,
I've searched for this and haven't come up with much other than the same error code for a bunch of other vehicles, and a bunch of different responses. My Tacoma is a 2000 PreRunner, 3.4 liter engine. The exact code I get it is: P1071 bank 1 system too lean Anyone know what this could be? Thanks in advance for any and all help! Sorry if this has already been posted and I missed it in the search. |

Re: P1071 Error Code
It is likely that you misread it and it is P0171. That is a common code for that engine
System too Lean (Bank 1) Possible Problems When the air fuel ratio feedback is stable after engine warming up, the fuel trim is considerably in error on the LEAN side (2 trip detection logic) Air intake hose loose Fuel line pressure low (may be from running out of gas) Injector blockage HO2 sensor malfuction MAF meter or MAP sensor malfunction Engine coolant temperature sensor malfunction Clean MAF meter with electronic circuit cleaner or replace<= most likely Fix vacuum/intake leak downstream of MAF meter Inspect fuel lines for cracks, leaks, or pinches Replace fuel filter Check fuel pressure at the fuel rail Check output of HO2 sensor Check injector performance Check ECT sensor Check PCV valve and hose fittings for tightness Most likely problem is dirty or contaminated MAF sensor.
