It is the coldest here it has been in years -23 celcius. When I started my 1999 Dodge Caravan LE the service engine soon light stayed on. Could the cold have anything to do with this? Also it is time for an oil change. Please help.
When it got real cold outside my temp light, gas gauge, and my speed meter don't work, can you tell me what is a TCM on my van I had it trouble shoot at the store but the guy didn't know what it means = it was a P1698

the service engine soon light(ses light) only comes on when the computer has detected a fault in the system and sets the light on and a code in the computer.you will have to have the code pulled to find out were to start your diagnosis to repair.
OBD-II Trouble Code Technical Description A P0020-023 code refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car's PCM (powertrain control module). That consists of an oil control valve (OCV), also called a solenoid valve and other components. Basically the check engine light and associated P0020-023 trouble code means that the voltage in the circuit has fallen below a set limit for a specific amount of time (varies by make/model/engine). Bank 2 is the side of the engine that doesn't contain cylinder #1.
Causes… A code P0020-023 may mean that one or more of the following has happened:
Faulty oil control valve (OCV)
Open or short in the VVT/VCT circuit
Open or short in the OCV / solenoid valve
Damaged computer (PCM)
Possible Solutions Some recommended troubleshooting and repair steps are:
Carefully inspect the Bank 2 VVT/VCT system circuit wiring and connectors, repair as required
With a warm engine, test the operation of the OCV, replace/repair as needed
ok, if the airbag light is on, there is a fault with the unit, your concerns are valid, if it has a faulty sensor the airbag MAY fire for no reason or not fire when you actually need it. if it has a recall on it, take it to the dealer so they can rectify the fault.
Recalls are a warranty repair from the manufacturer if they try to charge you scream the joint down
It comes on when the key is turned on to show it works, then it goes out as soon as the engine is started, it has a fuse, that will be marked, if the fuse is ok then you may have either a bad connection at the cluster connector or a bad ECM
