This may sound odd, but did you rermember to keep your "PROM" from your original ECM? It is the memory for all the ECM codes and configuration. The new ECM normally doesn't come with a PROM.

2003 ctdi goes into limp mode


code p0238 refers to manifold absolute pressure (MAP) sensor A TC system --high input===causes --wiring short to positive --MAP sensor---ECM
Replace the sensor (internal fault)
code p0102 refers to mass air flow (MAF) sensor /volume air flow (MAV) sensor --low input ===causes wiring short to ground ---MAF/VAF sensor
again the MAF is implicated as faulty

code po113 refers to intake air temperature (IAT) sensor--circuit malfunction===causes --wiring open circuit/short to positive --wiring short to ground --ground wire defective---IAT sensor---ECM

Now looking at all the codes the most common fault is wiring damaged so pay particular to the condition of the wiring loom --the condition of the connections --clean pins - pins not bent --water in the connections . IT is common that when disconnecting the units that the connection is pulled apart by pulling on the wires .. This check is the cheapest before any money is spent on the rest . Do not clean but replace because if cleaning does not produce a result you still do not know if you cleaned it properly or if it is faulty

Hello, Have a look at your Crankshaft and Camshaft sensors. As I remember there was a problem on some Chevies with the Crank sensor and it caused a different problem with the timing. But it probably could cause more problems so its' suspect.

While you did the filter and Regulator for the fuel, did you do a fuel sample? Also some of the ECU's can be refreshed and it is possible that you lost some info in the main computer and just need a reload of the program.

Although you changed the Intake manifold gasket, did you do a Vacuum check or mist the Vacuum lines while the engine ran? You should see if the Vacuum reading is okay. Then see if there is a Vacuum leak somewhere.

I hope my solution is very helpful to you. It looks like you spent quite a bit to solve this.

I have a 98 blazer the service engine soon light came on & I lost power I managed to limp it home. Changed cap, rotor, igintion coil, spark plugs & wires still running crappy. What next can someone...


could be fuel pump, fuel filter, air filter, o2 sensor though not usually all of a sudden. could also be that the distributor may have loosened and turned a 16th of an inch or more which would have caused this as well. check this by making sure your number one plug wire on the distributor is toward the number one plug on the motor. also you could have jumped time. check your belt or chain.

Coils and wires are the most likely culprits as they never get replaced hardly ever. You cant really test a coil, you can check for resistance on the plug wires but that doesnt tell you if the insulation is bad on them.

I have 8000 miles on my Tucson check engine light came on at start up this morning...gas cap is tight...no problems?????


there are over 200 reasons for the check engine light to come on, the gas tank cap is just one of them, this light and the problem that turned it on are most likely covered under the federal emission warranty, contact the dealer. see trouble code list below for some of the probelems that cause a check enghine light.

What engine? Sounds like maybe timing chain jumped or it is very lean.

Won't start. Runs terrible. changed plugs,wires,fuel pump,coil. plugs smelled of gas and were blackened.


Not terribly familliar with honda cars but most systems use either a cold start injector or just richen up mixture through the normal fuel system. This is controlled by a temperature sensor, either separate from or part of dash gauge sensor. I'd begin looking for that. If its always in "cold start" if will give you symptoms like yours. If not fuel injected, check choke operation. This may not be a "cure" but it's a good place to begin looking!
