Volvo 240, 2.3i CAT fra 1993 (Teknik #2848)
David Dollas • 2005-02-12 19:27Jeg en sådan bil. Motoren sætter ud, og jeg har så fundet ud af følgende fra en engelsk haynes bog. ---------- * PLEASE READ THIS FIRST * The following general procedures are to be used if driveability problems are encountered after power loss or battery has been disconnected. These procedures may provide an aid in eliminating these problems. To reduce the possibility of complaints, after any service which requires battery power to be disconnected, vehicle should be road tested. COMPUTER RELEARN PROCEDURES Vehicles equipped with engine or transmission computers may require a relearn procedure after vehicle battery is disconnected. Many vehicle computers memorize and store vehicle operation patterns for optimum driveability and performance. When vehicle battery is disconnected, this memory is lost. The computer will use default data until new data from each key start is stored. As computer memorizes vehicle operation for each new key start, driveability is restored. Vehicle computers may memorize vehicles operation patterns for 40 of more key starts. Customers often complain of driveability problems during relearn stage because vehicle acts differently then before being serviced. Depending on type and make of vehicle and how it is equipped, the following complaints (driveability problems) may exist: Harsh Or Poor Shift Quality * Rough Or Unstable Idle * Hesitation Or Stumble * Rich Or Lean Running * Poor Fuel Mileage These symptoms and complaints should disappear after a number of drive cycles have been memorized. To reduce the possibility of complaints, after any service which requires battery power to be disconnected, vehicle should be road tested. If a specific relearn procedure is not available, the following procedure may be used: Automatic Transmission * Set parking brake, start engine in "P" or "N" position. Warm-up vehicle to normal operating temperature or until cooling fan cycles. * Allow vehicle to idle for one minute in "N" position. Select "D" and allow engine to idle for one minute. * Accelerate at normal throttle position (20-50%) until vehicle shifts into top gear. * Cruise at light to medium throttle. * Decelerate to a stop, allowing vehicle to downshift, and use brakes normally. * Process may be repeated as necessary. Manual Transmission * Place transmission in Neutral position. * Ensure emergency brake has been set and all accessories are turned off. * Start engine and bring to normal operating temperature. * Allow vehicle to idle in Neutral for one minute. * Initial relearn is complete: process will be completed during normal driving. Some manufacturers identify a specific relearn procedure which will help establish suitable driveability during relearn stage. These procedures are especially important if vehicle is equipped with and electronically controlled automatic transmission or transaxle. Always complete procedure before returning vehicle to customer. ---------- Hvordan gøres det på denne volvo ? Det er med manual gear. Jeg har skiftet kobling og derefter er det som om at motoren sætter ud. Har checket alt. Svinghjulet sidder korrekt, tændrør har det godt, alle tændrør er med, strømfordeleren har det godt. Motoren er af type F. Hjælp ønskes... :)

Hvordan har svinghjulsføleren det?
#2868 David Dollas • 2005-02-13 14:52
Ja, jeg går ud fra at den har det godt. Den ser ren og pæn ud, og er som den skal være... Jeg kan ikke lige se at den skulle have problemer...

Ren og pæn er desværre ikke = et godt helbred for elektriske sensorer. Under dit koblings skift og afmontering af svinghjul kan det tænkes at du har ramt giveren, eller har du afmonteret den? med hjælp af bare lidt vold, aka. en skruetrækker. Problemet kan også ligge i stikket. En simpel ohm måling og visuel kontrol af forbindelserne kan sige meget. Morten

Har du så en ide til hvordan jeg måler den sensor... Men jeg har virkelig være "sød" ved den, ved afmontering og montering...
