SOURCE: trouble codes

Hi Sandra!
The trouble codes listed are defined as:

P0141 Oxygen Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)

P0300 Random/Multiple Cylinder Misfire Detected

P0331 Knock Sensor 2 Circuit Range/Performance (Bank 2)

PO300 & PO331 are possibly symptomatic of issues caused by PO141, which would have a direct influence on the air/fuel mxture... which could cause missing and knocking.

So the first thing I would try is replacing the Bank 2 Oxygen Sensor, after making sure the wiring and connections to that sensor are in good shape.

Does the engine show any physical issues such as loosing coolant, smoking exhaust, overheating? A blown or leaking head gasket on the #2 bank could also present these (among other)
codes.

Good luck and let me know how it goes!

WB

SOURCE: WHAT TO DO ABOUT TROUBLE CODES PO449 & PO141 ON 01 VENTURE

code is P0449

The PCM has determined that a malfunction exists in the electrical circuit for the vent valve/solenoid in the evaporative emission control system.

Definition:
EVAP (Evaporative Emission System) purge/vent solenoid circuit condition

Explanation:
The solenoids and system wiring are monitored for opens or shorts

Probable Causes
1- Purge or vent solenoids defective
2- Check connevtor and wiring
3- Fuel saturated vapor canister
4- Failed EVAP vent solenoid


A code P0141 may mean that one or more of the following has happened:

  • open or short to ground in the wiring harness
  • O2 heater circuit wiring high resistance
  • O2 heater element resistance is high
  • Internal short or open in the heater element
Note: Typically a failed catalytic converter does not cause this code. You're more likely to see a P0420 code for a failed converter.
Possible Solutions
  • Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)
  • Repair short or open or high resistance in wiring harness or harness connectors

PO171 and P1131 point to lean codes on bank PO174 and P1151 point to lean code on bank PO305 is missfire on cyl 5

the lean codes is probably a vacuum leak or maybe a MAF sensor is bad or dirty

missfire is dependant on engine if a V10 it may be a coil actually pretty likely on the modulars not uncommon thats for sure
sorry forgot to add that its says missfire on #5 cant remember if that one is the first on the left or last on the left facing the engine vacummn leak could be those dang auto hubs got it stuck in the mud and they did not engage I need to buy some new ones took them apart to clean them out this summer

1998 bonneville engine hesitation


Is there an illuminated check engine light on the dash? That sounds like a failing TPS (throttle position sensor). Unless you have low fuel pressure! When (if ever) have you replaced the fuel pump and/or fuel filter? Are you running the correct type of fuel in the engine? If you have slow or sticky fuel injectors, a can of Seafoam might help!

My check engine light come up w/ all these code P0305,P0440,P0441,P0446 what's wrong Thanks


po305 is related to missfire on #5 cylinder
po440 is related to fuel tank pressure
pO441 is for evaporator purge flow malfunction
po446 relates to vent control valve electrical circuit malfunction

missfire is seperate from the other codes
as for the other three codes replace the vent control valve solenoid located near the charcoal canister the oth3er codes can relate to a faulty solenoid

after replacing light will only go out if you clear through a scan tool or three drive cycles of over 10 min each

These are misfire codes.This means that your vehicle is missing.The 300 is a random misfire and the 305 is for cylinder 5,and the 306 is for cylinder number 6.Check the plugs if they are good then you could have bad coils.They are top of the plugs.Hope this helps.Good luck.

Misfires and codes PO316, PO306, & PO305 popped up on the diagnostics check. What needs to be fixed based on that?


You will need to replace no 5 and no 6 coil pack and spark plugs. P0316 is random missfire that computer could not detect the cylinder that was causing it,just knew one was missfiring.
Coil packs are common concern on these vehicles. Can get oil leak into the coil pack wells and may also even get moisture into them.
If yours is a 3.9L it may be involved in owner satisfaction program 07M07 or 07N09 in which they will cover them under the program for up to 10yrs or 100000 miles which ever comes first.

Does it drive ok? You may need to just clear the codes. Try disconnecting the battery and connecting again this will reset the codes. If it comes on again let me know and I can try to help some more. Thanks
