Pull the codes from the computer, match the code to the troubleshooting procedure, follow the procedure to find the source. Repair the source, light will go out if that was the only problem. There are "monitors" or self test the computer runs the car through, if a problem occurs, it may not run all of the self tests until that problem is taken care. Therefore, another problem may exist. It is emission related.
you replaced speedo, so try replacing speed sensor
Have the code read. Autozone will do this for free. Even though the light is not on now. It will be stored as a recent code. It has to cleared to be erased completely. Good luck. i had the same problem with mine it turned out to be the knock sensor i replaced it and the problem went away give that a try
When this happened to me on my seven year old 2.2 DCi laguna I had to hae taken in to the Renault dealers. It turned out to be the a problem with both the cam sensor and the fuel injection sensor. Both had to be replaced at a cost 0f £300 in all. It did cure it though! May also be TDC / crank sensor. Worth removing it and giving it a clean.
Depending on the year it could be in the distributor or by the crank's pulley. On 93-98 Honda passports with the 3.2l engine the crankshaft position sensor in located on the passenger side of the engine near the engine mount. 93-95s did not have the camshaft sensor though. that was added in 96 and is located on the d/s valve cover in the outside upper corner
You need to reset the light by using diagnostic equipment even though the part was replaced the fault code will still be stored in the ECU memory.
I dont know what codes you were getting. double check the connections. And get the code cleared. retry it. If it still comes on reread the code to see what it says. You didnt get anything on tips of the o2 sensor did you? Another thing the rear one refers to the one after the Cat converter. Is that the one that was replaced? People sometimes forget this. If there is still a probplem the circuit has a prblem. The code would be saying this though. Hope this helps.
The O2 sensor is located on the rear exhaust- driver's side. Easiest to get to if you rotate the engine forward and away from the firewall. I have used regular wrenches even though they sell O2 sensor wrenches.
Unscrew the bolt through the centre of the sensor & unplug the wiring connector. Re-fitting is the reverse of removal. More often than not the knock sensor is not faulty though, the engine is knocking due to low oil level.
Sounds like head gasket is leaking allowing coolant into combustion chamber
On our '92 the light comes on when the water level in the resovor is low. If you have the correct level of coolent possibly your sensor could be bad. Try filling the plastic resevior if it is low. There is a sensor on top of it that makes the light come on even though the temp is not hi.
It wouldn't make much of a vacuum leak to cause the engine to idle at high RPM. First check for vacuum leaks even though you may still have good manifold vacuum.
Which sensors have you replaced, these cars have 2 of them. One located on the thermostat housing, and one located on the rear of the block under the exhaust manifold.
A faulty temperature sensor can cause the ECm to think your engine is overheating, this turning the heat light on constantly. You should make sure that your engine isn't in fact overheating though.
It would be recommended if coolant had mixed with the engine oil before the head gasket was replaced.
had similar prob i had to replace # 4 cylinder and my entire cam pack on my engine...obd reader are sweet to have ..get one made for any vehicle.they are $$$, but saved me 780.00
I have a magna Executive with a o2 sensor. I have been having problems with ever since I had to replace the main computer under the dash. I keep getting chech engine wring lights on my dash. Since then I have had the engine checked and the o2 sensor repalced only thave to problem come back to me again and again and going back to the dealer. So I disconnected the sensor from the engine to the computer and the engine still starts and I get excelleration and the car runs, though it does run sluggish and feels fuel strvations is there, but yes you can run the car without the o2 sensor especially in a Magna TR....
Have you had your 4 oxygen sensors replaced? It turns out when they replaced my oxygen sensors, they were after market parts so the service engine light did not come and gave codes even though they were replaced.
cheap back up to crank sensor. it may allow the car to run with out crank sensor, though poorly
we can i don't know if we are though.... its hard to answer..... we will just have to wait and see.
When the low coolant warning light comes on and the car has enough coolant, it usually means there is a problem with the coolant level sensor system. The sensor may need to be replaced.
P0320 (M) No Crank Reference Signal at PCM No reference signal (crankshaft position sensor) detected during engine cranking.P0320 (M) No RPM Signal to PCM (Crankshaft Position Sensor Signal to JTEC) A CKP signal has not been detected at the PCM.The Sensor has failed. Replace the *Cam Position* Sensor in the Distributor.***added by DrStoooopid You're half right. The sensor has failed, but there's two of them.1. Cam position sensor, which is on the front of the engine. (location varies depending on engine)and is most definitely not in the distributor. There IS no distributor in those engines, they're electronically controlled. The cam position sensor sits .30" from one of the camshafts.2. CRANK position sesnor which that code is referencing. The CRANK position sensor is the one that failed. (They usually fail in pairs though). The crank position sensor is harder to get to. It's on the back of the engine, near the transfer case.
When there is a code in the computer the engine runs on a set of specs and is not variable. Get the 02 fixed.
yes it was replaced by a monument though
In the 2002 Dodge caravan with a 3.3 liter engine where the 8th digit of the vin is a 3 the crankshaft position sensor is located on the top right side of the transmission bellhousing. If you are looking into the engine compartment on the Driver's side place your head directly to the right of the ignition coils and look down at the bellhousing of the transmission. You will see the sensor there though it is slightly hidden by the exhaust crossover pipe.
ohm it out at the connector on the right side of the engine. if it is no continuity it is bad. it has very high ohms though so you need a good meter.
