When the adjustments become too large to maintain the proper mixture, the fault codes P0171 and P0174 are logged. The Engine Control Module measures the amount of oxygen in the exhaust system via the oxygen sensors and makes adjustments by adding more or less fuel to the mixture. "Lean" Mixture: Too much air, not enough fuel "Rich" Mixture: Too much fuel, not enough air A mixture that isn't optimal may be called: Your engine operates at an optimal fuel/air mixture that is controlled by the Engine Control Module.

Repairs that can fix a P0733 code would include: It is best to have this code diagnosed and repaired as soon as possible to avoid further damage to the vehicle and to prevent being stranded anywhere.

This code can cause a number of drivability issues and is very likely to leave the driver stranded on the side of the road somewhere. For whichever route gets taken, the labor will be expensive, so it is best to make sure the transmission actually needs to be replaced before adding even more money to the bill. It is important to be certain that the transmission is faulty before replacing it. Common mistakes when diagnosing the P0733 codeĪ mistake that could easily be made when diagnosing a P0733 code would be to have the transmission replaced assuming that internal damage has occurred. Some of the parts of the transmission that may need to be inspected or tested are not accessible without transmission disassembly. The diagnosis of this code is likely to involve the complete teardown of the transmission, or at least the removal of the transmission pan. If the fluid level and condition are acceptable, the next thing the mechanic may do is perform a test drive to confirm the customer’s symptoms.

Some of the potential causes of the P0733 code may include: If there is a difference between the desired gear ratio and the actual gear ratio (multiple times) a Check Engine Light will be illuminated. The powertrain control module uses the information it receives from multiple sensors that gather and calculate data, such as vehicle speed, throttle position, engine RPM, and other measures to determine which ratio a particular gear should have. This will usually have to happen multiple times before a trouble code will be stored. The P0733 code means that the powertrain control module (PCM) has detected something unusual with the ratio of the third gear in the vehicle’s transmission. Gear 3 incorrect ratio is the technical definition of the P0733 trouble code What the P0733 code means
