First check for spark at any of the sparkplugs and if you have spark then check your fuel pressure.This will help narrow the problem down.Let me know what area the problem is in whether it be ignition of fuel.

SOURCE: reset the computer system of 2001 chevy venture

Unhook the battery for about ten minutes or so... if you have an after market stereo that requires a code make sure you know it.

Had the ignition module replaced on my 99 chev venture and has created more problems like peeping and then hesitation in trying to go forward

Who replaced the ICM ? Check engine light on or flashing ? Without looking the vehicle over an doing some testing , would only be guessing as to what the problem is . Are wires hooked up correctly ? What's the fuel pressure ? Hooking up a scan tool that can view engine sensor data parameters should be done , checking for vacuum leaks , checking fuel trims - short & long term trims . Are the O2 sensors switching normally ? Why was the ICM replaced ? Didn't start an run ?

Trac Off light and Cooling Fan running on my 2001 Chevy Cavalier

I had the same problem on my 2001 Sunfire (same car as the Cavalier-different branding) which I was able to fix successfully.

My symptoms were:
-Traction Control OFF light illuminated
-Cooling fan running even if engine cold and it was freezing outside (I also noticed that when the Traction light illuminated, the fan would then begin)
-Rough idle with black smoke when cold
-Poor fuel economy


I have a code reader which produced codes P0130 and P0171. These are error codes for the upstream oxygen sensor (the one under the hood).

I simply replaced the O2 sensor (it took me 10 minutes). I did not reset the check engine light after the repair as I wanted to see what the car would do on its own. The idle was much smoother with no smoke and the cooling fan stopped running unnecessarily. After 1/2 mile down the road, the Trac light went away and the system functioned normally. I tested this by trying to accelerate quickly up a snowy driveway. I also noticed that the acceleration and shifting (auto tranny) were smoother. I reset the check engine light. All is satisfactory.


What was happening to the car before the repair:

P0130 is usually for a bad O2 sensor and P0171 is the sensor detected that the motor was running too lean (but it actually wasn't-the sensor was essentially giving a false lean signal).
The rough idle, black smoke, and poor economy are due to running too rich. In my case, the sensor told the PCM (the car's computer) that the air/fuel mixture was too lean. In response, the computer said "OK, more gas!" That's why it ran rich. This was evidenced on the old O2 sensor as well...it was completely caked with carbon from an excessively rich mixture. This further destroyed the performance of the O2 sensor.

Can a bad downstream oxygen sensor cause a rough idle on a 2003 chevy venture

no, the downstream sensors do not feedback into the control of the engine--they only detect the effectiveness of the catalytic converters. If the sensor is detecting excess fuel, the problem could be with your fuel pressure regulator, and that would also explain the rough idle. Do you have a trouble code you can pass to me?

2000 chevy venture doesnt start

check to make sure the security light is not on if it is the van will have spark but no injecter pulse the best way to solve this issue is to have the original igniton key and put it in the igniton in the run position and leave it on for 10 minutes then the light will flash then try to start the van

I ran a Diagnostic on my 1998 chevy venture mini van and here are the codes that came up, P0102, P0134. What does this mean? I have already replaced the following, fuel pressure regulator, both crankshaft...

the 2 codes are

P0134 02 Sensor Circuit no activity Detected (bank 1 sensor 1)
first check your fuses check the wiring to the sensor(the sensor is on the exhaust in front of the engine-open the hood and look down) if the fuses and the wiring look good replace the O2 sensor there are 2 types of sensors original equipment(oe) style and universal the oe style has a connector you just plug in, the universal you have to hard wire in

the 2nd code is Mass Air Flow (MAF) Circuit Low Input
check the wireing, make shure theres a good connections
you said that you already replaced this sensor so im going to recomend that you go after the other code first

deal with the oxygen sensor then reset the computer and see what codes come back

2001 chevy venture engine hesitating

there could be several reasons for this type of problem. the engine is controled through main computer(ECM) and the sensors assocciated with it. most often times a hesitation is commonly a idle issue and that would be monitored by the TPS ( throttle position sensor) if this is beginning to fail it sends faulty reradings to the computer and the computer tries to compensate and sometimes either leans or richens the fuel air mixture cause and effect is a engine stall or a hesitation. another factor is your (O2) sensors these monitor your exaust and tell the ECM to adjust accordingly the fuel mixture also. a sure fire way to tell if one ore more sensors are faulty is to either have your check engine light come on or if there is a rough start. if the check engine light isn't on then i would think there is a timing issue involved and a tune up is in order. the tune up is simple by just changing plugs and wires, however the timing is computer controled and can only be adjusted by a certified tech with the proper equipment. try and change the plugs and wires first this is the least expensive way to solve your problem. if the problem persists then take it to a shop and have a tech hook up diagnostic tools to check the ecm for fault codes to narrow down whatsensors if any are faulty.
