What is the code 171 mean on my dodge ram 1500


P0171 Chrysler - Fuel System Lean

Possible causes
- Intake air leaks
- Faulty front heated oxygen sensor
- Ignition misfiring
- Faulty fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Faulty Mass Air Flow (MAF) sensor
- Incorrect Positive Crankcase Ventilation (PCV) hose connection

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 replaced the air filter and clean the air flow meter. If the problem persist the front oxygen (O2) sensor may need to be replaced.

When is the code detected?
- Fuel injection system does not operate properly.
- The amount of mixture ratio compensation is too small. (The mixture ratio is too lean.)

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


P0171 Chrysler Description
With the Air/Fuel Mixture Ratio Self-Learning Control, the actual mixture ratio can be brought closely to the theoretical mixture ratio based on the mixture ratio feedback signal from the heated oxygen sensors 1. The Engine Control Module (ECM) calculates the necessary compensation to correct the offset between the actual and the theoretical ratios.

In case the amount of the compensation value is extremely large (The actual mixture ratio is too lean.), the ECM judges the condition as the fuel injection system malfunction and light up the Malfunction Indicator Light (MIL) (2 trip detection logic).

Codes po171 and po522 on my dash board


P0171 Fuel system lean bank 1, P0522 Engine oil pressure/switch circuit low voltage. Take care of the P0522 get the oil pressure check out first. As for P0171 that can be from a vacuum hose leak from false air.Worn out sparkplugs. To a contaminated MAF(mass air flow sensor).Lean bank is a easy fix but low oil pressure get that look at.

What does engine code po171 on a 2007 chrysler pacifica mean


A P0305 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. Did the codes appear after the new plugs/wires were installed? What about new Dist. cap and rotor?

Did you use quality parts?

Check for vacuum leaks (including manifold gaskets) on Bank 1 (Driver's side).

Also swap Cyl.#5 injector with another cylinder and see if the misfire code changes.

Are you sure #5 plug is firing?It's possible the cat may be restricted, but I would first swap #5 injector with another cylinder and check for vacuum leaks.

A plugged cat/exhaust system will not set a P0171.I'd say first check the intake manifold gaskets (two of them) for leaks. There are other things that could be causing those common but pesky p0171 and p0174 codes. I would recommend you search the forums on those two codes as they're pretty common.

The P0442 code is likely not related

2003 Chrysler Town & Country po171 code


DTC P0171 - System Too Lean (Bank 1)
Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1.

Note: This DTC (Diagnostic Trouble Code) is very similar to P0174, and in fact your vehicle may show both codes at the same time.

I would suggest that you take a look at the front oxygen sensor. Typically speaking the oxygen sensor causes this code to appear. Here is the possible cause list from the manual for your car.

Trouble Code: P0171 (2.5L V6 Auto) - Fuel System Lean (Bank 1)

Possible Causes:
Air leaks in intake manifold, exhaust pipes or exhaust manifold
Base engine mechanical problem causing a lean A/F condition
Fuel control Sensor is out of calibration (e.g., ECT, IAT or MAP)
Fuel delivery component fault (clogged filter, low fuel pressure)
O2 element is contaminated, deteriorated or it has failed
Vacuum hose is disconnected, broken, leaking or loose

Hope this helps (remember to rating this answer ans leave us a testimonial comment). Thank you for using FixYa.
