I've been chasing this gremlin for about a year and a half now and posted about it a few times. Over that time, I have replaced the rear wheel speed sensors, the front hubs and the front abs sensors came pre-installed in the new hubs. I've done enough research to write a book on the subject as well. It pulled out C and U I've had it apart, cleaned the tone wheel, and made sure everything else was clean. The wiring looks great and the connector is tight. Does anyone have any ideas of what could be left to look at or fix? Posted: Mon Oct 11, pm. I'm just going to long shot bump this one I just did a mile road trip and really miss cruise control! Did you trace the wiring between the wheel sensor and the ECM? Maybe it rubbed through somewhere in between? Posted: Sun Apr 07, pm. I am currentley facing the same issue. I have the U error read at O'reileys which. I ordered a new front sensor which is just a guesse. I have did the key on position off on again 3 times and it displays 5 or 6 dashes then states done. So no codes on the self diagnosing program. But I have a tie rod that needs replaced and I am wondering if the loss sway bar has caused steering to come off center and prompt the traction control ABS BAS lights?? Posted: Tue May 14, pm. I just fixed one of these! Looks like it could be a common problem for this vehicle if you have a manual trans. Hope that helps. Color scheme by ColorizeIt! Logo by pixeldecals.

Post a Comment. Left rear tone wheel damage. Axle shaft fastener hardware. Left rear WSS. Caution : Make sure braking capability is available before road testing. Does the scan tool display CA-Left rear wheel speed comparative performance active? Turn the ignition on, with the scan tool, monitor and graph all the WSS speed and compare graph while an assistant drives the vehicle. If graph shows periodic dropouts pay close attention to the tone wheel. No, the condition that caused the symptom is currently not present. Inspect the related wiring for a possible intermittent condition. Lock for any chafed, pierced, pinched, or partially broken wires. Perform the ABS Intermittent condition. Step 3. Check and adjust all other tire pressures, inspect for mismatched tires on vehicle. Is the Left Rear improperly inflated or mismatched tires on vehicle? Yes, repair as necessary. No, go to step 4. Step 4. Check axle shaft fastener hardware for looseness Inspect the axle shaft fastener for looseness, and not properly fastened. Tighten fastener to properly specification as required. Was the Axle Shaft fastener loose? No, go to step 5. Step 5. No, go to step 6. Step 6. Is the Left Rear Wheel speed sensor damage? Yes, replace sensor and hub assembly. No, go to step 7. Step 7. Check Left Rear tone wheel for damage Inspect the Left Rear tone wheel for damage, missing teeth, cracks. The tone wheel teeth sould be perfectly square, not bent, or nicked.

C engine code seems a kind of chassis problem, we try to show one by one the meaning and the solution. Brief explanation of the C code and definition of C is the bottom side. MFG - Manufacturer Specific codes, which have a '1' as their second digit to indicate they are unique to a particular vehicle make or model. These special codes were deemed necessary by the vehicle manufacturers so they could provide additional diagnostic information beyond the basic list of generic OBD II codes for all kinds of faults, not just emissions-related faults. Deactivation of cylinders is achieved by releasing a synchroniser pin that normally interlocks the cam follower and rocker arms. C code resolves the synchroniser pin is released using hydraulic pressure which is controlled by a dedicated solenoid. Regarding the C code, it would probably be worthwhile to carefully inspect the wire harness near the intake manifold bracket. This is done most easily from below the car in the area near the oil filter. When you see C engine fault code on your engine code reader this description will help you. Final Step: In the definitions listed below, there is a test drive recommended after you've completed any repairs to see if the condition is fixed. Before you take a test drive after a repair, always erase the C Code s first. This will turn the check engine light off and then you will know if the check engine light returns, you've got further diagnostics to complete.

These special codes were deemed necessary by the vehicle manufacturers so they could provide additional diagnostic information beyond the basic list of generic OBD II codes for all kinds of faults, not just emissions-related faults. There are currently two main types of cylinder deactivation used today, depending on the type of engine. C code for the pushrod design which uses solenoids to alter the oil pressure delivered to the lifters. In their collapsed state, the lifters are unable to elevate their companion pushrods under the valve rocker arms, resulting in valves that cannot be actuated and remain closed. The oxygen 02 sensors on your car measure the oxygen in the exhaust to determine how rich or lean the ratio of fuel and air are in the cylinders. Optimizing this mixture means better fuel economy and fewer exhaust emissions. When you see C engine fault code on your engine code reader this description will help you.
