SOURCE: Code error P1361 Honda CIvic LX 2002

P1361 TDC Sensor Intermittent Interruption (I got this from Engine-Light-Help.com)
TDC should mean Top Dead Center.
It is the sensor that tells the computer the #1 cylinder piston is at the very top. And therefore, fires the spark plug.

Since the maintenance done above, I believe the the timing marks for the timing belt is not lined up properly. Being off by one tooth will cause this problem.

SOURCE: When driving my 2002 silverado my lights will dim

Most likely it is the voltage regulator in the alternator . this is common of a alternator be for going bad, some times this is caused from jump starting.rarely it could be a intermittent short. but it would save a lot of time to have the alternator Thrilley tested or even replaced.it really don't mater about the volt out put.if the reg. is failing .hope this helps .if you want any further assistance feel free to ask.we are here to help.

2002 chevy blazer wont start when temperature falls below 20, when I turn the key on I can hear the selenoid cliking but the starter wont turn over head lights dont dim sometimes after trying a few times...


Start by cleaning the battery terminals with baking soda. Start with the negative, then positive. Then reconnect the positive and then negative. If you can remove the battery vent caps check for low acid level. Fill with distilled water if low.

Chevrolet blazer problems


Usually bad brushes in the alternator. They will make intermittent contact and cause the light to go on and off. I would replace the alternator.

Alot of the time the AntiTheft Security system can actually turn OFF your starter. Do you see a light on the dash that reads SECURITY? If so, then this is 100% your problem. This link explains it and offers some "do it yourself" solutions http://vatspasslockpasskeysecurityhelp.yolasite.com/

My 2000 Chevy Blazer battery light is on. This


Could be anything from corrosion on cables, loose cables, lose or faulty wiring of wires behind alternator
defective voltage regulator. Visually inspect all the items noted. Then use a volt meter and measure the charging voltage of the alternator. It must be between 13,5 to 14.5 volts with and without accessories on at idle and 2000rpm. Anything below 13.5 weak battery or defective alternator ,lose wiring , corrosion. Anything above the 14.5 volts is a defective regulator.
