Fuel injectors do go bad and stick in the open position.<\/p>\n<p>Identify the failed fuel injector.<\/p>\n<ul>\n<li>Remove all spark plugs<\/li>\n<li>Turn key to the on position- cycling the key may be required<\/li>\n<li>Take note to which cylinder fills with <a href=\"\/\/www.freeautomechanic.com\/fuel.html\">fuel<\/a><\/li>\n<\/ul>\n<h2>READINESS MONITORS\/DRIVE CYCLES<\/h2>\n<p>HO2S and Air Fuel Ratio (A\/F) Sensor Monitor and Readiness<br \/>\nMonitor<\/p>\n<p>NOTE: All readiness monitors are cleared when the battery is disconnected or when the<br \/>\nECM\/PCM is cleared with a scan tool.<\/p>\n<p><strong>Drive Cycle Procedure<\/strong><br \/>\n1. Connect the scan tool.<br \/>\n2. Turn the ignition switch ON.<br \/>\n3. The MIL must be OFF.<br \/>\n4. The Engine Coolant Temperature (ECT) and the <a href=\"\/\/www.freeautomechanic.com\/iat-intake-air-temperature.html\">Intake Air Temperature (IAT)<\/a><br \/>\nshould be greater than 41\u00b0F (5\u00b0C).<br \/>\n5. The Engine Coolant Temperature (ECT) and the Intake Air Temperature (IAT)<br \/>\nshould be within 10 degrees of each other.<br \/>\n6. Do not turn the ignition switch off during the procedure.<br \/>\n7. Most OBD monitors will complete more readily using a steady driving style during<br \/>\nthe acceleration and cruising modes. Operating the throttle in a smooth method<br \/>\nwill help ensure and assist completing the monitors.<br \/>\n8. The fuel tank should be between \u00bd and \u00be full with \u00be full being the most desirable<br \/>\nlevel.<br \/>\n9. Start and idle the engine for five (5) minutes with the A\/C and rear defroster ON.<br \/>\n10. Turn the A\/C and rear defroster OFF and idle the engine until the Engine Coolant<br \/>\nTemperature (ECT) sensor reaches a minimum of 170\u00b0F (76\u00b0 C).<br \/>\n11. Begin driving and accelerate the vehicle until the vehicle speed is 56 mph (90<br \/>\nkm\/h).<br \/>\n12. Release the accelerator pedal and keep it released for 10 seconds or more.<br \/>\n13. Accelerate again until the vehicle speed is at 56 mph (90 km\/h) and continue<br \/>\ndriving the vehicle at 53 &#8211; 60 mph (86 &#8211; 96 km\/h) for 10 minutes.<br \/>\n14. Check the monitor for \u201cCOMPLETE\u201d status. If the monitor status is not<br \/>\n\u201cCOMPLETE\u201d, go to the next step.<br \/>\n15. Decrease vehicle speed to 0 mph (0 km\/h).<br \/>\n16. Let the vehicle idle at 0 mph (0 km\/h) 60 seconds.<br \/>\n17. Accelerate to 30 &#8211; 35 mph (50 to 55 km\/h).<br \/>\n18. Drive the vehicle between 30 &#8211; 35 mph (50 &#8211; 55 km\/h) for 5 minutes.<br \/>\n19. Decelerate to 0 mph (0 km\/h).<br \/>\n20. Let the vehicle idle at 0 mph (0 km\/h) for 45 seconds.<br \/>\n21. Drive the vehicle at 53 &#8211; 60 mph (86 &#8211; 96 km\/h) for 5 minutes, holding the<br \/>\naccelerator pedal very steady. Monitor the Throttle Position Sensor (TPS)<br \/>\nvoltage; it should be between 0.8V and 1.2V.<br \/>\n22. Decelerate (coast down) to a stop without braking.<br \/>\n23. Let the vehicle idle at 0 mph (0 km\/h) for 45 seconds.<br \/>\n24. If the readiness monitor is still set to incomplete, check for a temporary DTC. If<br \/>\nthere is no DTC, one or more of the enable criteria were probably not met; repeat<br \/>\nthe procedure.<br \/>\n25. Allow the vehicle to sit (key OFF) for 8 hours and repeat the procedure.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This car has 170,000 miles on it.
