Lean fuel injectors-Refer to Fuel Injector Solenoid Coil Test See: Powertrain Management Computers and Control Systems Testing and Inspection Component Tests and General Diagnostics Fuel Injector Solenoid Coil Test. I took my 2007 Outlook to a dealer, verified the p0017 code with digital diagnostic meter, the service personnel even conducted more extensive diagnostics and nothing out of the ordinary or anything remotely significant was identified. These including: an engine that runs poorly, an engine that cranks but will not start and an illuminated check engine light. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. .
So, begin your diagnosis by visually inspecting the sensors and their connections. Can I drive it until after Christmas or is this a ticking tmebomb? Cranking the engine, you should see the voltage reading on the meter fluctuate. What are the symptoms of the P0018 code? You should see a reading of about 12 volts indicating a good ground. Diagnostic Aids If the condition is intermittent, move the related harnesses and connectors, with the engine operating, while monitoring the scan tool circuit test status parameters for the component. Following these tests should help with your diagnosis without replacing the parts that are still good. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors. This allows optimal catalyst efficiency under light load conditions at a steady cruise.
Small oil leak, unknown where it is coming from. Then, check that the 5-volt reference is getting to the sensor by connecting the red multimeter lead to the reference voltage pin and the other to ground. It is located closer to the exhaust manifold and before the catalytic converter. This part is also sometimes called Chevrolet Traverse O2 Sensor. If you need to dig into your doors, dash or console, Alldatadiy. Additional comments for consideration regarding the P0018 code Code P0018 is the same as code P0016 except for the opposite side of the motor. What causes the P0018 code? How serious is the P0018 code? Start by consulting the wiring diagram for your vehicle to determine which pin on the connector is which.
In most cases, this will involve engine disassembly to the point of failure. Then, use the correct oil and oil change interval to prevent future damage. Start by consulting the wiring diagram for your vehicle to determine which pin on the connector is signal and which is ground. You should see a reading of about 12 volts indicating a good ground. The timing relationship synchronization of the two sensors will be distorted if a timing belt jumps time, a cam gear slips, a timing chain gets loose or a cam phaser misbehaves. Upstream O2 sensors are located between the engine and the catalytic converter and monitor exhaust as it comes from the engine, sending data to the engine control computer.
Inspect the sensor pigtail or the harness for contacting the exhaust system. Both the underhood and instrument panel fuse boxes are located on the passenger side of the vehicle. Next, connect the red multimeter lead to the battery positive terminal and the black lead to the ground pin. Many also offer bi-directional testing of the solenoids with just the push of a button. Removing the timing cover and checking that the timing marks line up is one of the first things to do. The best way to test cam and crank sensors, as well as their synchronization, is with an oscilloscope.
This tells the computer how well the catalytic converter is performing. Set your meter to the ohms setting — you should see a value appear on the screen. If there is no change in the reading, the sensor is bad and should be replaced. Verify that none of the following conditions exist: Exhaust system leaks-Refer to Exhaust Leakage See: Engine, Cooling and Exhaust Exhaust System Testing and Inspection Exhaust Leakage Engine vacuum leaks Low fuel system pressure-Refer to Fuel System Diagnosis See: Powertrain Management Computers and Control Systems Testing and Inspection Component Tests and General Diagnostics Fuel System Diagnosis. The cel came on and stays on permanently. Repair Instructions Perform the Diagnostic Repair Verification See: Verification Tests after completing the diagnostic procedure.
In addition, the solenoids can also be removed and jumpered to battery voltage to confirm operation. Running fine but recently started throwing code P0017. The B sensor is likely on the exhaust side. Cracked reluctors and missing reluctors can also lead to an altered waveform pattern. Any suggestions would be much appreciated. Diagnostic Procedure Instructions See: Testing and Inspection Initial Inspection and Diagnostic Overview Diagnostic Procedure Instructions provides an overview of each diagnostic category.
You should see a reading of about 5 volts indicating a good reference voltage. Common mistakes when diagnosing the P0018 code? Plus, they contain full trouble code descriptions and troubleshooting instructions. What repairs can fix the P0018 code? The cam phaser was replaced along with the timing guide. The closed loop fuel control is active for greater than 1 second. How do you troubleshoot code P0017? P0036, P0037, P0038, P0056, P0057, P0058 The ignition voltage is between 10-18 volts. The engine load is 17-65 percent and steady. The solenoid circuit should also be tested for proper power and ground.
Consult the manufactures repair information from a source such as for the resistance specifications. Repair Instructions Perform the Diagnostic Repair Verification See: Verification Tests after completing the diagnostic procedure. Bad sensors will hamper performance, economy and increase emissions. Remove the sensor connector and attach the meter to the sensor terminals. Note: The manufacturer's tests may help to to narrow down the problem.
If you find any of the above conditions, repair as necessary. Timing chain problems seem to be common on the four-cylinder engine. Note: The ignition circuit supplies voltage to other components. What are the common causes of code P0017? Timing belts can stretch over time and mileage, and are flexible enough to skip time. An example of a cam and crank pattern Courtesy: aa1car.
