1998 mazda b2500
I am getting a p1131 code when I run a scan that says lack of ho2s11 switches sensor
indicates lean, the truck will not stay running without a lot of throttle manipulation, which
sensor should I replace?
Upstream sensor not being heated (HEGO) Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank 1 next, - Vacuum leak affecting bank 1 only - Fuel injector problem bank 1 - Check for cylinder misfire on bank 1 - Engine mechanical condition - Faulty O2 sensor. Over 80,000 miles change it then rescan for codes
