Question about Cars & Trucks
I am not able to check engine codes anymore. read-out gives me link-error. No spark control. Engine kill relay will not energize.
Well that all points to a faulty computer.
You could buy a used part from a salvage yard, or do a pin test on the one you have. You'll need a shop manual to get the wiring diagrams and specs.

Charlie. You have replaced the ECM on your van?.
Kedwin,, Your problem is, the computer on that 3.3 L.
Need to be programed with the VIN nember of your car.
The Antitheft System will disable the injectors due a incorrect VIN, Bucause the body computer is not recieve the correct pasword between 5 seconds after start up.
YOU have 2 options. 1 get a ALOHA Smith. some of they have the computer required to program ECMs.
The other option is: Get a new ECM from the dealer, They will program if ask for that.
NOTE:::::: Other way is . Put the body control module with the computer from the same car.
OK... I hope this work for yours.
If NOT letme know I can look for more information.

Don't rush to replace the fan itself until you have tested it. Check the fan relay and relay fuse inside the vehicle. Hopefully it will be just a failed relay and replacement ($12 at dealer) or/and an inexpensive 10amp or 30amp fuse. There can be multiple issues causing this code.
In my case, the fan relay failed (burnt). 2000 Dodge Durango. The PCM was also damaged and requires replacement, awaiting delivery. A remanufactured PCM can be purchased online for substantial less than at the dealer. We tested the fan by supplying power directly to the fan and it runs fine. We had to remove a cover (easy to remove) under the vehicle near the fan to gain access to the connector Use a fused link for testitng to prevent damage during the test. Using a multimeter, I found power 12.5volts from the 30amp fuse circuit which supplies the power for the fan, 12.5 volts from the PCM circuit with the key on, but only 5.16volts from the 10amp fuse circuit with the key on. A continuity test showed the 10amp fuse inside the fuse box inside the vehicle was good. The 30amp fuse in the power distribution box was good when tested for continuity. Checked resistance on all curcuits and they were well within limits. I also checked the wiring to the fan for continuity and resistance. After my tests were completed, a Dodge technican concluded the PCM is bad and is not grounding the circuit as it should. If you want to troubleshoot this yourself, see if your local library has access to ALLDATA which will have diagnostic information and the diagrams of the circuit involved. A Haynes manual for the vehicle, I purchased one at Autozone, can be helpful also.

That code dsoesn't 100% mean the sensor is defective, other factors can set it. See list below.
Possible causes- Camshaft Position Sensor harness is open or shorted
- Camshaft Position Sensor circuit poor electrical connection
- Faulty Camshaft Position Sensor
- Faulty starter motor
- Starting system circuit
- Dead (Weak) battery
P0601 CHEVROLET - Power Control Module Internal Fault
Cause: Faulty PCM. (Powertrain control module)

Check fuses first, but could be needs new CPU
Posted on Jun 15, 2012
Testimonial: "Thanks for your help, we checked the fuses even swapped out the relays. The CPU was a thought but someone else tried it and it didn't work. Might still try it though. Is there any other symptoms that would indicate the CPU is bad? We changed out the ignition switch, 135.00, changed the CPS, 42.00. I hear the CPU is about 150.00. When we run the tester it comes back with no error codes."

Battery or power line recently disconnected - This code is normal if the electrical system has been worked on or the battery has recently been disconnected. It will be removed after 15 ignition switch on/off cycles.
Low system voltage, bad battery or battery terminals - If the system recently had a power drop (due to a dead battery or bad alternator), this code will appear. If the battery terminals are bad and the engine was jumped, this code will appear. See the Diagnosing Your Charging System page for more information.
Bad connection or wiring - Check the wiring and connections between the battery, power module, and logic module (or SMEC). Check all fusible links and power connectors to the battery. Clean and regrease any corroded connectors with dielectric grease and repair any shorts.
Code 32 - Logic module did not see a change in air/fuel ratio when EGR circuit was activated - Possible CausesEGR valve stuck open or closed - If the vehicle fails emmisions, then the valve may be shut. If the enigne runs poorly at low rpm or at idle, the valve may be stuck open. It may be the valve or the transducer valve. Test the transducer valve vacuum output. At idle, the transducer valve vacuum should be mostly bled, and there should be very little, if any vacuum at the output. When the engine is revved, the vacuum should increase. If the transducer is functioning properly, replace the EGR valve.
Bad EGR solenoid or Canister purge/EGR solenoid - The solenoid is located in the right, front fender next to one to three other solenoids. See the Understanding Solenoids page for information about how to test and repair solenoids.
Bad connection or wiring - Check the wiring and connections between the solenoid and the logic module (or SMEC). Clean and regrease any corroded connectors with dielectric grease and repair any shorts.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
Thank you for using FixYa, have a nice day.

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.
To confirm the problem, the basic troubleshooting is required.
