P1701 Possible Causes 1 Faulty Transmission Control Module (TCM) 2 Transmission Control Module (TCM) harness is open or shorted 3 Transmission Control Module (TCM) circuit poor electrical connection
What causes the p0171 code to go bad?
Mass Air Flow Sensor – The mass air flow sensor calculates the volume of air entering the engine. If it has gone bad, the air fuel mixture will be off and the P0171 code will show. Bad Fuel Injectors – If you have one or more fuel injectors that have gone bad that can certainly cause the air/fuel mixture to go bad.

When to use lean condition code p0171?
Combustion engines run most efficiently when they maintain an air-fuel mixture ratio of 14.7 parts air to 1 part fuel. When there are more than 14.7 parts air to 1 part fuel in the air-fuel mixture, a lean condition exists and code P0171 is triggered.
What does lean fault code p0171 mean on a car?
Your car or truck has either a P0171, P0174 lean fault code or both stored in the pc, these codes derive from Oxygen Sensor (O-2) readings. A lean code or codes suggest that there surely is too-much air in the exhaust.
The cost to diagnose the P0174 NISSAN code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
Is it okay to drive a Nissan with p0171?
It is okay to drive your Nissan with P0171 for a short period of time, but driving with this code for an extended period of time can overheat the engine and cause internal engine damage. It is important to complete the entire diagnostic process when diagnosing P0171.

What is the cause of Hyundai p0171 air leak?
It is important to complete the entire diagnostic process when diagnosing P0171. Many people will replace the air fuel sensor or O2 sensor as soon as they get a bad reading, but the root cause is often a dirty or faulty mass air flow sensor or vacuum leak, thus causing the O2 or A/F sensor to read differently to compensate.

What causes the p0171 Nissan fuel injection system to leak?
P0171 NISSAN Tech Notes If the P0171 is combined with the P0174 code, it’s very likely that the problem is caused by an intake leak. If there are no intake leaks, the next step is to replace the air filter and clean the air flow meter. If the problem persists the front oxygen (O2) sensor may need to be replaced.
