However, also includes disassembly instructions for interior trim panels and exterior items like headlights and tail lights. Bobdec thanks as well, I agree I think it's something in the wiring or sensor in the fan clutch, because it would throw codes while the key is on but not running, and then when fan clutch electrical connector unplugged no codes and engine ran fine. Part Number 89024920 Description Harness Assembly, Engine Cooling Fan Wiring Thank you for using fixya. This contact may damage the insulation of the wires enclosed in that harness. Refer to Circuit Testing and to Wiring Repairs.
P2135, P2138 and P0641 out of the blue
Starting letter P diagnostic code shows that there are problems in engine, transmission and emissions systems. As the speed of the fan increases, the voltage must also increase. I put a fair amount of dielectric grease on both sides, and connect and unconnect the plugs a few times. Plus, they contain full trouble code descriptions and troubleshooting instructions. Did you find and correct the condition? In that case, low power steering fluid is typically responsible. To find out if the sensor is the thing causing the problem, use the power brake booster sensor connector and use the digital ohmmeter to check sensor resistance.
P0526 Code
Feed the wires into the slot and install the harness to the plastic guide. Repair or replace harness as necessary. Is the voltage measurement near than the specified value? Without the ability to keep the powertrain at the optimum level, the engine will most likely overheat and become inoperable. Your mechanic will use a brake booster pressure sensor to assess how much braking assist pressure is present for bringing your vehicle to a halt. Ensure to test for poor connections and pin retention at all inline connectors. Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model to another. I erase the trouble codes to clear them, and notice that I'm getting new trouble codes without even starting the engine.
P0526 OBD
But before changing anything, do a thorough cleaning of the throttle body first, make sure to clean the front and rear sides. It's the original fan clutch with over 200k miles, and has been acting a little sluggish the past few months, so it was an easy decision to swap it out. Since then I have avoided idling as much as possible just as a precaution. I get home, plug in the code reader and sure enough one trouble code about fan circuit being bad. Unbelievably, I get no trouble codes when I switch the key to run.

I actually got the fan clutch nut loosened fairly easily, it was the water pump pulley that was a medium pain, I had to break out the oxy torch and warm it up, then pry off slowly with a pry bar. How does a mechanic diagnose the P0556 code? I repaired that line with some copper tubing and compression fittings, that's actually the first time I've done that and it was really a lot easier than I expected. There should be resistance between the two wires. These have been known to be bad out of the box. Refer to Testing for Intermittent Conditions and Poor Connections and to Connector Repairs. In some rare cases, you may not notice any symptoms at all. If the code is a reoccurring code, narrowing down the underlying cause can help with future repairs.
P0621
Common mistakes when diagnosing the P0556 code As we mentioned above, this code may be triggered because hydraulic brake boosters fail. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. I actually had have a couple of instances in the past few years where I noticed the fan running longer than normal when driving while cold, but not nearly enough to make me think, I should change that fan clutch. Transmission shifted ok, but seemed a lot different. The fan is running loudly, engine running fine, no engine codes. Also fan was louder than normal. Replace the harness with an improved design Part No.

The fan will turn at speed for a bit when cold and then quiet down, no matter if it's plugged in or not. Here's a video on how to test the fan clutch using a rag. I get in, and find myself staring at a christmas tree. Disconnect the harness electrical connector from the cooling fan clutch. Then I notice while driving at some point, the fan quiets down, almost like normal.

The best part about this job, was checking for leaks after all was done, and finding transmission fluid running out onto the ground. I read about the cooling fan harness fraying issue and want to check that next morning, this thing has electrical problem written all over it. How serious is the P0526 code? Stop the fan like in the video but keep holding it. I'm going to order in a new fan clutch, and water pump as well once I do more research on changing a water pump. Also, at the moment, you may not mind having to put a little extra effort forward to slow your vehicle, but it could get progressively worse and eventually surprise you, which would be extremely dangerous. Slide the new position sensor on, then reinstall shafts.

Did you find and correct the condition? Ensure to test for poor connections and pin retention at all inline connectors. Plus I'm thinking I may as well change out the water pump, it's the original also. Answer: Yes, it does sound like the steering wheel position sensor is faulty. So, like I mentioned I can turn the fan manually with the engine off. I examine the connector and harness again, and can't really see any visible problems. I think the fan clutch sensor or electrical connector was wacking out on me. Also disconnect the battery while doing the cleaning, this will reset the computer to factory defaults and allow it to relearn to the cleaned throttle body.
