Saturn Cars & Trucks - Page 8 - Answered Questions & Fixed Issues

moved you to Saturn the book on it is here and covers all that and 10,000 more;. https://eautorepair.net/Marketing/Default.asp the PCM does all that. so those pages are bingo no engine told. ok 3.6L V6 if USA car.? if you do cars all the time you learn that the schematics are not simple like 80s back.! (newer cars have like 3 to 10 computes now. ECU/PCM /TCM/BCM and more. so have many pages, on that connected IGN and spark. and stater, no problem told so not telling that I can not guess what pages matter to you. your PCM runs 6 cop coils (all 6 dead?) COIL Over PLUGS. use ckp and cmp sensors that make that happen. and timed. the car may have IMMO secuirty keys, and if key lost or bad the IMMO goes dead killing dead, spark and fuel. never have just one key some have battery in the key dead. look? the users guide covers all that key jive. no problem told, my car has 7000 page factory service manual and 100s of pages just on PCM and related pars. 100s sorry not posting them all.

ok mech. , join a real Saturn forum.? rule #1 is fuse first. all must be good. what does gauges dead mean sure ,meters dead but is the cluster dead, IP cluster 100% dead, and CEL lamp self test key on dead.>? scan it yet? that is rule 2 (assumes battery is good /charged) scan it but DLC OBD2 Pin 16 needs 12vdc and fuse blow there scan tools are born dead. back to rule #1 again. does engine crank and run and drive.? do head lamps work? does the radio work. ? heater blower blows.? and is the ODOM dead./?????????/ if comm's or fuse dead) new battery not connected backwards now or before. many electronics blow up backwards, see some do have a diode on the VCC/VDD rails in electronics to stop that but some do not.! to diagnose any car made we take note of all things good , bad or ugly seen. all facts matter and reduce the testing needed. all matter, even head lamps work key on or off. many clusters now are on a CAN bus, network BINGO HERE> , ONE OF HE FIRST IN USA. USA spec, car or NOT. (gm exports cars ww) I will now punch up L300 in the service manual just for you gauges.? speedo dead tachmeter ded fuel dead engine temp, dead? ODOMETER DEAD that too is meter but proves power and can bus not dead if works, does this work ? here is the FSM page words for how that all works "The instrument cluster receives information via the Class 2 serial data link from the 4 cylinder (L61) Body Control Module (BCM), the powertrain control module (PCM), and the sensing and diagnostic module (SDM). On V6 (L81) engine applications, the information from the engine control module (ECM) and the transaxle control module (TCM) is sent to the BCM over the CAN serial data link where it is converted to a Class 2 message and sent to the cluster. The information from the electronic brake/traction control module (EBTCM) is sent to the BCM, where it is converted into a Class 2 message and sent to the cluster." NOW THE NITTY GRITTY FACTS HARD ign1 FUSE NOT BLOW OR IP IS DEAD, ZERO POWER TO IT. the can bus nor serial class 2 bus must not be dead. or IP goes dead. all needle meters go dead too. like that or fuse IGN1 dead. or PCM /ECU nor and more. the whole IP runs off a network. real. and very modern that year. IGN1 fuse must not be blown.

There are multiple computers in the car that have to talk to one and other. There is the ECM or ECU and it talks to the BCM. Sounds like the BCM is having issues.

cars, check fuses first the scan the PCM see error there YOU WILL but you forgot to look first then ask the blind to guess. the brake pedal (not emergency) does that ,it is shifter lockout. on all modern cars. a lockout solenoid on some clicks the operators guild told you to step on brake and shift out of park autmatic trans not stick shift manual transmission. do not break the brakes;. speedo dead is 1 of 3 things (beside stated blown fuse) 1: IP cluster bad or wires on back fell off. 2: IP cluster CANBUS network dead. 3: speed sensor VSS1 dead. in all 3 cases the scan tool tells you all that in seconds flat.

• buy the tool
• rent on .
• barrow one.
• or as the shop to scan it , repeater here 10,000+ times but sure nobody searches...

USA OBD2 scan tools. vast choices, endless. ,hand held or simple PC or phone adapter.

There is more to then just replacing the lifters, pushrods need to be measured to see if they are bent, they need to be measured for length wear, the lash needs to be set, the springs should be tested. Best thing to do now is a cylinder leak down test to see if the valves are all seating correctly etc.

which engine is it. and USA car? did you even look first. seems not to me. why not go to Valvoline oil changers, and let them do the mess. no split oil. here it is, me reading your manual < LOST IT: ?

2004, 2.0L or 2.2L engine? chain drive cam, no cam belt. manual trans shift or automatic, (guess AUTO) will not crank (starter motor is silent ) and crank shaft does not spin, 1: check all fuses first. 2: try cranking Park if fail try Neutral. (hold brake pedal to shift) 3: the IP cluster, is the security lamp glowing wrong? PASSLOCK LAMP glows see below. red arrow. this failing , means the key is bad. but only blocks fuel not the starter. https://assets.gm.com/manuals/saturn/2004_saturn_ion_owners.pdf A: do head lamps glow, bright even key off and HL turned on. B: battery lugs clean C :battery voltage (use a meter) read 12.6vdc rested D: jump cable , jump starts work:? (call tow truck ask for a jump) E: use a scan tool , scan the PCM see the errors (DTC)? F: that is enough for now, (the are lots of fuses to fail. and there is more. like starter relay #31 bad.? and crank fuse#46

step1 check all fuses step2 scan the PCM no car can diagnosed lacking the scan tool. the TCM shifts,it why would you ignore the errors it stores. be pain that, or get the car fixed in a shop.

The fuel tank and lines are under the back seat. Seems to be a known issue. https://www.google.com/search?q=2006+Saturn+VUE+fuel+line+routing ..

The diagnostic trouble code (DTC) P0420 "Catalyst System Efficiency Below Threshold" is one possible outcome following the Catalytic Converter Monitor (test). This monitor is one of the last tests to be performed by the powertrain control module (PCM) because other failures in the system could compromise this test's result. Catalyst efficiency is tested by observing the oxygen sensor signals both before and after the catalyst. Before the catalyst, the signal should appear as a sine wave as it switches back and forth between rich (0.9 volts) and lean (0.1 volts). After the catalyst, the signal should be flat-lined on the rich side (about 0.7 volts). This is because a healthy catalyst will store oxygen and therefore remove the "lean" portion of the signal/waveform. If the signal after the catalyst still appears as a sine wave, the PCM concludes that the catalyst can no longer store oxygen and should therefore be replaced. In your specific scenario where a downstream (post-cat) O2 sensor was just replaced, I would theorize that this sensor had failed and was flat-lined. Then when it was replaced two things happened: 1.) the oxygen sensor began to work properly which allowed the oxygen sensor monitor (test) to complete, and 2.) the catalyst monitor then ran and used the new (accurate) sensor data to determine that the catalyst efficiency was below threshold.

There could be a lot of reasons. One could be that the air vent actuator is moving. Set the air management controls on a different setting and see if that changes the clicking.

Drain the tank & add fresh fuel check wiring to starter motor & check starter motor not burned out

downstream after cat conv

This is a bad sign, usually means that the first gear in the transmission is out.

You need to ascertain where the oil is coming from the Rocker Cover Gasket or the PCV valve? https://www.google.com/search?q=2008+saturn+astra+xr+replace+rocker+cover+gasket Replace the gasket and see if it continues. It is a pain to replace the PCV according to this. You may be able to clean it with carburetor cleaner when the rocker cover is off. https://www.google.com/search?q=2008+saturn+astra+xr+replace+pcv+valve ..

This is a common problem on GM vehicles. This security light indicates a failure in the antitheft system that comes standard on your vehicle. It miscommunicates with itself and then shuts down the vehicle as a protective measure. There is no recal on this. The dealer wont help you.
