Po411 2000 cadilac catera po411 secondary air flow

Secondary fan injection on199 Cadillac catera not coming in ?????

What do you mean ? Secondary air injection ? 199 Cadillac catera not come in ? Not coming on ?

What do you mean by fuel regulator ? the one that is on front on top of the engine? with two chambers and a flapper that is electronically controlled

cadilac in the suzuki section, oops.

Since this car was built in Germany, I would recommend getting a service manual first.

Hello there :
Inspect for dust or contaminants on the sensor: see the picture with the arrow.
Using an ohmmeter, measure the resistance between terminals THA and E2. Resistance: At -20 °C (-4 °F) 13.6 - 18.4 KOhm At 20 °C (68 °F) 2.21 - 2.69 KOhm At 60 °C (140 °F) 0.49 - 0.67 KOhm

2. Inspect the intake air flow meter operation.

1. Connect the intake air flow meter connector.
2. Turn the ignition switch to ON.
3. Using a voltmeter, connect the positive (+) tester probe to terminal VG, and negative (-) tester probe to terminal E2G.
4. Blow air into the intake air flow meter, and check that the voltage fluctuates.

P0411 is secondary air incorrect flow. THis can be corrected by replacing the air bypass valve, GM # 9192121.

P1890 is the throttle position sensor (input)

P1781 is the engine torque signal circuit.

While driving should be ok I certainly wouldn't embark on a long road trip.

The hot air from your aircon usually has nothing to do with freon. I'm not sure about your particular car but usually there is a 3/4 inch valve near the rear of the engine to regulate hot water flow to the heater radiator under the dash. This valve can sometimes seize up. If it is a vacuum controlled valve, check that the vacuum lines are connected and not split.

hi let me see if i can find one.(i work at a junk yard)

how to set a timing on a cadillac catera 97?
