There's a black plastic valve below the battery that fails frequently on these cars. It has a vacuum line and 2 thumb-sized hoses going to it. A lot of times the valve will be broken in half and obviously bad. This will cause a secondary air injection code. Also the vacuum hose to it needs to be intact. Check this stuff first.

No- air flow meter is fitted in the air pipe next to the air filter,secondary injection could be the air pump (a big box with an air pipe going to the engine)you can sometimes hear them when you start your car from cold or the valve that it blows into could be stuck open which would reduce your airflow and give you a code for low airflow or volume,why did you replace your lambda reply to vagman54@btinternet.com if you need more help

1 Answer

96saab 900s check engine light on code p1115 replaced rear 02 sensor then replaced front o2 sensor check engine light came back on.


you will also need to check the wires coming off both o2 sensors and also sometimes the main CPU gets fried always sending those codes

I replaced my secondary air check valve on my 2001 chevy tahoe but code 1416 still comes up. what else can i check


here is what i found on p1416.



P1416 Chevrolet
P1416 Chevrolet - Secondary Air Injection System Bank 2
Possible causes
- Faulty Secondary Air Injection (AIR) pump
- Secondary Air Injection check valve bank 2
- Secondary Air Injection (AIR) pump electrical circuit fault
- Blocked Secondary Air Injection (AIR) system

When is the code detected?

The P1416 code is set when no O2 sensor voltage change is detected by the Engine Control Module (ECM).


Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)


P1416 Chevrolet Description
An Secondary Air Injection (AIR) pump is used on this vehicle to lower tail pipe emissions on start-up. The PCM supplies a ground to the AIR pump relay, which energizes the AIR pump. The Powertrain Control Module (PCM) monitors the HO2S voltages to diagnose the AIR system. During the AIR test the PCM activates the AIR pump during closed loop operation. When the AIR is activated, the PCM monitors the HO2S voltages and short term fuel trim values for both banks of the engine. If the AIR system is operating properly, the HO2S voltages should go low and the short term fuel trim should go high.

FORD FOCUS CODES 136; 491; 1131


You might want to search for more info online - - code 136 and 1131 are for O2 sensor problems. Code 491 is for secondary air injection flow out of range. The EGR system controls the emissions in the exhaust by injecting air into the exhaust. The computer is not "seeing" the O2 sensor(s) switch back and forth and there is a problem with the secondary air flow. The air flow problem could cause the other two codes. I think the 491 and 1131 are Ford specific codes.

Odb2 will not pwr up my snapon scanner on a 95 saab 900s


The OBDII Scanner will turn the ignition key forward but don't start vehicle and turn all lights and radio off and heater off. And plug the scanner in. Then it will run the codes and tell you what code(s) are write them down. Then you will hit the erase button to reset your engine light. If the light goes back on you have a problem it should stay off up to 50 miles if not then have your vehicle checked out usually it could be your O2 sensors or a MAF Sensor "MASS AIR FLOW SENSOR" that is faulty and or your intake tubes are loose allowing too much air flow in to the engine if this happens your car will be running too lean.

Good Luck!

OBD2 code P0171 MAF sensor too lean (98 Saab 900 SE Turbo)


The maf sensor is either dirty, or needs replacing. Try cleaning it first.
Disconnect the black tube from the air filter housing, and the sensor housing, there should be a thin wire going across inside, get a can of air intake cleaner (at any auto parts store) and spray it in there, be very careful when you wipe that wire off. wipe off any excess cleaner inside.
If the same problem still exists, change the sensor.

Code 1128


P1128 on Motronic (1996 900 S) indicates multiplicative adaptation fault > 22%. Symptoms are poor driveability, hunting idle speed, possibly in combination with other DTCs (e.g. low fuel level, MAF (mass air flow sensor just behind the intake filter), misfiring).
WIS instructs one to 1st check wiring harnesses and connectors for places where shorts may have developed. Visual inspection results should be verified with multimeter. Check all air hoses and vac lines for leaks. Also check the throttle body o-ring which is a known problem. Check the evap purge cannister. Finally, electrically test the MAF.
