What are the fault codes for fuel trim?

Fig. 1 above shows the fuel trim data collected on a vehicle with the Check Engine light on and fault codes P0171 (Bank 1 System Lean) and P0174 (Bank 2 System Lean) present.

What should bank 1 fuel trim be at idle?

If long-term fuel trim (LTFT) for bank 1 is 25% at idle, but corrects to 4% at 1,500 and 2,500 rpm, focus on factors that cause a lean condition at idle, such as a vacuum leak.

What causes a Ford Escape to run rich?

When the oxygen sensor is bad, it can cause a false reading and trigger the code. The computer will still adjust the air/fuel mixture to compensate. This will cause the Escape to run rich. Mass Air Flow Sensor – The mass air flow sensor calculates the volume of air entering the engine.

What causes a Ford Escape to misfire at idle?

Misfire – If the air fuel mixture has gotten too far from factory specs, this can cause the Escape to misfire. Idle Issues – With the air/fuel mixture altered, the vehicle can idle erratically as the computer compensates to keep the engine running. This youtube video is a great resource for diagnosing the P0171 trouble code in your Escape.

What causes the p0171 code on a Ford Escape?

Oxygen Sensor – The P0171 codes is thrown when the oxygen sensor (s) do not register enough oxygen in the exhaust. When the oxygen sensor is bad, it can cause a false reading and trigger the code. The computer will still adjust the air/fuel mixture to compensate. This will cause the Escape to run rich.

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.

P0446 Ford Escape. One of the most common trouble codes with the Ford Escape is the P0446 code. This trouble code references a number that is given to you when you plug your Escape into a OBDII scanner. P0446 Indicates that there is a fault in the evaporative emission control system.

What is the diagnostic code for fuel level sensor malfunction?

P0460 is a diagnostic trouble code (DTC) for “P0460 Fuel Level Sensor Circuit Malfunction”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

What is the code for Ford diagnostic trouble?

Refer to our Generic OBD II code list for definitions on all other Ford diagnostic trouble codes. P1000 OBD System Readiness Test Not Complete P1001 KOER Test Cannot Be Completed P1039 Vehicle Speed Signal Missing or Improper P1051 Brake Switch Signal Missing or Improper P1100 Mass Air Flow Sensor Intermittent

What is the OBD code for fuel pump?

P0230 is a generic OBD-II code which indicates that the fuel pump primary circuit has a malfunction of the vehicle power to the fuel pump when it is commanded on or off.

What to do if the OBD II scanner doesn’t communicate with the vehicle?

What to do if the OBD II scanner doesn’t communicate with the vehicle. TEST 1: Connect the positive DMM lead to DLC pin 4 and the negative DMM lead to the negative battery terminal, using jumper wires if necessary. Do not connect to the body or chassis ground but to the battery terminal directly.

What should I do if my fuel sensor is not working?

If any faulty, corroded, broken or disconnected wiring has been detected in the electrical circuitry related to the fuel sensor, it should be fixed or replaced as needed. The fuel tank ground and connections with the PCM should be cleaned thoroughly as well to promote a better current.

What is the diagnostic code for cylinder 2 misfire?

P0302 is a diagnostic trouble code (DTC) for “Cylinder 2 Misfire Detected”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

What does it mean when engine Bank 2 is too lean?

A lean condition is brought about by an imbalance in the air to fuel ratio due to either insufficient fuel (from, say, a weak fuel system) or excessive air entering the engine. The bank 2 portion indicates that the problem is concentrated on the side of the engine opposite the #1 cylinder. The error codes for these conditions are P0171 and P0174.

What does a trouble code on a cylinder mean?

If a trouble code for that cylinder is stored by the powertrain control module, this indicates that the wire or coil pack is causing the misfire. When other trouble codes related to the misfiring issue are present, these need to be diagnosed and repaired as well.

What is the code for O2 sensor misfire?

Code PO302 refers to a misfire. P1153 refers to the O2 sensor not switching often enough. This sensor monitors how often a lean to rich condition or rich to lean condition is present.

What does code p0171-system too lean mean?

Code P0171 – System Too Lean: Symptoms, causes, common problems, diagnostic. The OBDII trouble code P0171 – System Too Lean (Bank 1) means that the engine air-fuel mixture is too lean, or there is too much air and too little fuel.

How does the EVAP system work on a Ford F150?

The EVAP system captures all fuel vapor from the fuel tank and sends them to the engines intake in order to be ignited in the normal combustion process. When the EVAP control system vent control circuit no longer responds to the ECU, it will throw the P0446 OBDII Code, and the service engine soon light will illuminate.

How to reset the EVAP system monitor drive cycle?

Connect the Scan Tool to the data link connector (DLC). Use the Scan Tool to clear any stored DTC’s and to reset the Onboard Diagnostic Monitors. Bring up the Readiness Code for the EVAP System Monitor. 2. Start the engine (cold); IAT PID from 40-100ºF (this step requires a key “off” period of at least 8 hours). 3.

When does EVAP turn off the ignition switch?

EVAP SYSTEM MONITOR DRIVE CYCLE INSTRUCTIONS Do not turn off the ignition switch during the test procedure. All Onboard Diagnostic Monitors are cleared when the battery is disconnected or when the Powertrain Control Module (PCM) is cleared with the Scan Tool.

Ford and Mazda decided to offer a car-like, unibody design with a fully independent suspension and rack and pinion steering similar to the RAV4 and CR-V, the Escape.

What was the 4 wheel drive system on the Ford Escape?

The four wheel drive system was a newer version of Ford’s “Control Trac” 4×4 system, dubbed the Control Trac II 4WD in the Escape. This system allowed the front wheels to receive 100% of the torque until a slip was detected. Using a Rotary Blade Coupling, the rear wheels could be sent up to 100% of the power in fractions of a second.

What to do if your Ford Escape coil pack is not working?

There is a really easy test to determine if it is the primary or secondary wiring that has thrown this code in your Escape. Move the ignition components (coil pack, plug wire, plug) from cylinder D/4 to another and clear the codes. If the code “moves” from the fourth cylinder, you now know that it’s a secondary issue.

What causes Ford Escape to throw SPARK code?

The primary wiring is the wiring harness leading from your Escape’s ECM/PCM to the ignition system itself. A short, open, or poorly ground wiring harness is almost always what causes P0354 when it is the primary wiring side that has thrown the code. The secondary side of the equation is the spark side.

Where is the diagnostic port on a Ford Escape?

by Lee Sallings. The Ford Escape uses an OBD II diagnostic port located under the left side of the dash near the steering column. Pulling trouble codes requires the use of an OBD II capable code reader or scan tool, with the scan tool being preferable because it gives more diagnostic information than a code reader does.
