How do I fix error code P2197?
What repairs can fix the P2197 code?
- Repairing/replacing harness damage or corrosion.
- Replacing faulty ECM.
- Repairing PCV system leak (Replacing PCV valve and/or PCV hose)
- Replacing Mass AirFlow (MAF) sensor.
- Repairing/replacing ECT (Engine Coolant Temperature) sensor.
What causes a P2197 code?
The P2197 code is a result of the engine control module (ECM) indicating that the oxygen sensor is fluctuating outside its optimal range. This sensor is nicknamed the air/fuel (A/F) ratio sensor, as it monitors the air fuel ratio of the exhaust between the engine and the catalytic converter.
What is code P2198 mean?
What the P2198 code means. This trouble code indicates that the upstream oxygen sensor on the second bank of the exhaust is sending a reference voltage to the powertrain control module that is not within the range of acceptance set by the vehicle manufacturer.
What do codes P0171 and P0174 mean?
A trouble code P0171 or P0174 means the oxygen sensor or Air-Fuel Ratio (AFR) sensor (in bank 1 [P0171] or bank 2 [P0174]) has detected a lean fuel mixture: either too much air or not enough fuel is going into the engine. One or both of these lean-fuel condition codes can be set for several reasons: Worn fuel pump.
Can a bad air filter cause a check engine light?
A dirty air filter is one of the things that can cause your Check Engine light to come on, caused by an inadequate supply of air to the engine that results in a buildup of carbon deposits. Have your mechanic scan your vehicle to track down the source of the problem, as it could be as simple as replacing the air filter.
Can a dirty MAF sensor cause a check engine light to come on?
On the other hand, when there is too much fuel relative to oxygen (rich condition), the Check Engine light can be triggered. This condition can be caused by a dirty or faulty Mass Air Flow sensor, air filter, a blockage or restriction in the airstream, a fuel pressure, fuel injector or fuel delivery problem.
What’s the symptoms of a bad mass air flow sensor?
Symptoms of a Faulty Mass Air Flow Sensor
- The engine is very hard to start or turn over.
- The engine stalls shortly after starting.
- The engine hesitates or drags while under load or idle.
- Hesitation and jerking during acceleration.
- The engine hiccups.
- Excessively rich or lean idling.
What does a dirty MAF sensor cause?
A contaminated or failed mass air flow sensor cannot measure the amount of air flow correctly. This causes the engine computer to miscalculate the amount of injected fuel. As a result, a bad mass air flow sensor causes various driveability problems, including a no-start, stalling, lack of power and poor acceleration.
Can fuel system cleaner fix a misfire?
If it is a clogged fuel injector you may get lucky and the cleaner will fix that enough that the misfire goes away. If the problem is a bad spark plug or wire then it is going to do nothing. If it is a clogged fuel injector you may get lucky and the cleaner will fix that enough that the misfire goes away.
How long can you drive with a cylinder misfire?
50,000 miles
