I have a 2001 Civic LX, 150,000 miles on it
started having a hesitation issue when in Drive going from 1st to 2nd gear.

first code P1607 , at this point it was just the hesitation issue.

took to honda mech and we replaced a sensor sorry i have a blank when it comes to what it was. just under the battery. adn it cost$200



then after replacing that part. went about 30 miles and it really started doing some crazy stuff. these are the codes it thru this time

P1362 = No Signal In TDC 1 Sensor Circuit
P1259 = VTEC System Malfunction
P1607 = ECM/PCM Internal Circuit Failure A
p0325 Crankshaft Flux (knock) sensor (CKF)
P0122 = Throttle Position Sensor (TPS)
p0112 = Intake Air Temperature (IAT) sensor
P0336 = Camshaft Position (CMP) sensor

so my mechanic said lets do the Crankshaft and the TDC 1 sensor.
so we did that $300 later and through in a timing belt...

went bout 35 miles running great then , when i went to stop and go shifing either down to 3rd.2nd RMP drop drasticly like i put on the break.

then i get tot he stop and first the Click from under the dash,
then the "D" light goes out and it dies.

sometimes when i am taking on In "drive" it will hesitate going from 1st to 2nd and sometiems into 3rd. the Check engine like is spiratic. when it was
on I went to Autozone to get the codes read and it came up with nothing.
and the light was on...

I am at my wits end. This is getting old I love my Honda had my last one
for 16years. 1990 civic. wish i had it now.

I am running out money to fix this car, I only had it since Feb 2010. and i am about ready to SELL it and get a different one.

PLEASE HELP SOMEONE!!

It might be the ECM (computer). P1607 seems to be showing up more than once.

Has the condition of the battery and alternator been checked? Don't just replace those though without having them checked.

You might also want to seek another mechanic. Sounds like he was kind of guessing.

It's either a bad connection/wire to the ECM/PCM or you need a new ECM/PCM.

That's what I'm thinking. After all, what are the odds that all of the sensors fail at the same time? Pretty darn slim.

Check alternator mounting as well, due to the fact the alternator charging capcity function is regulated by the ecm. Several people on here have had their ecm fried due to the alternator not properly grounding.
