With the stay at home orders, I've been taking little trips outside to work on the car. Trouble codes said 33 and 45. MAP Sensor and Rich Exhaust, O-2 sensor.
I replaced the MAP sensor with a known good used one. No change.
So I buzzed over to AutoZone and got a new MAP and O-2 sensor. I installed the O-2 sensor first as it was the cheapest part. No change. I was still getting the 33 and 45 codes then suddenly the 33 and 45 went away and a 44 came up. Lean exhaust.
Looking around, I found a broken vacuum line from the MAP to the fuel pressure regulator. I repaired that, but I kept getting the code 44 every time I cleared the ECM.
Back down to AutoZone and get a Coolant Temperature Sensor for the ECM fuel management. No more trouble codes. So the new MAP sensor was never installed and will be returned.
Still needs the plugs and wires removed from the passenger seat and installed in the engine, though.
