My check engine light came on and I had the codes checked out, first was the coolant temp sensor, which I have replaced, then after a few days the light came back on, this time the CMP sensor was bad or intermitent, or timing belt needs to be repalced, the van has only 50000 miles, I had replaced the CMP sensor and the van worked for a while but my temp gauge went all the way up even if the engine was dead cold, the fans kicked in, I drove it for about 7 miles and the light came on again, I had the code checked and it was the same as the first time p0304. Should I replace the CMP sensro again.?.

code p0016refers to the crankshaft /cam shaft position sensor bank 1 sensor A-- correlation===causes---Wiring CKP sensor--CMP sensor--mechanical fault Check timing belt is not broken code po113 refers to intake air temp (IAT) sensor--circuit malfunction===causes ---wiring open circuit/short to positive--wiring short to ground---ground wire defective IAT sensor---ECM code mp0700 refers to transmission control system/MIL-malfunction===causes--wiring ---TCM code po562 refers to system voltage low==causes---wiring poor connections---battery---alternator or it also refers to ECM power relay control--circuit open===causes ---wiring--ECM ---relay. For this one check the battery terminals and posts are shiny clean and tight . Have a load test done on the battery to check for faulty cell. check condition of alternator drive belt and check alternator out put.
HOT WIRE COOLANT FAN. STILL DONT TURN ON REPLACE FAN ASSEMBLY. IF COOLANT FAN DOES TURN ON WHEN HOT WIRED.CHECK THE FAN RELAY OR FUSE ALSO SCAN VECHICLE FOR FAULTY COOLANT TEMPERATURE SENSOR IF ENGINE COOLANT TEMPERATURE IS 190 DEGREES AND SCANNER SHOWS 80 OR LOWER COOLANT TEMPERATURE SENSOR FAULTY.
P0128 - Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature)
This means that the engine's PCM detected that the engine has not reached the required temperature level within a specified amount of time after starting the engine. The intent of the P0128 code is to indicate a faulty thermostat. Similar codes: P0125
In determining the engine did not reach a "normal" temperature, it takes into account the length of time the vehicle has been running, the intake air temperature (IAT) sensor reading, the engine coolant temperature (ECT) sensor reading, and the speed of the vehicle.
Symptoms: You will likely not notice any drivability problems other than the MIL illumination.
Causes: A code P0128 may mean that one or more of the following has happened: * Low engine coolant level * Leaking or stuck open thermostat * Faulty cooling fan (running too much) * Faulty coolant temperature (ECT) sensor * Faulty intake air temperature (IAT) sensor
Possible Solutions: Past experience indicates that the most likely solution is to replace the thermostat. However here are some suggestions on troubleshooting and repairing a P0128 OBD-II code: * Verify coolant strength & level * Verify proper cooling fan operation (check if it's running more than it should). Replace if necessary. * Verify proper engine coolant temperature (ECT) sensor operation, replace if necessary. * Verify proper intake air temperature (IAT) sensor operation, replace if necessary. * If the above items check out good, replace the thermostat * If Nissan vehicle, check for Technical Service Bulletins (TSBs), as the ECM may need to be reprogrammed to correct the P0128 code
What signal is this? is this for a check engine light code?Okay i know what you mean, it a p0073 code, this is the ambeint temp sensor,this is the sensor that tells you the outside temp on your display, the sensor may be bad ,misssing or bad wire going to sensor,was this van in a crash, lots of times the sensor gets damaged from an accident,
the PO406 code is the EGR position sensor. I have heard tho that DMX corp had some issues with this code in the past where basically it was just tossing false codes. But they also did have a higher fail rate on them during 05-07, so you may have to replace it anyways.
