the check light glows at ever engine, stall, below about 300 rpm
the engine stalls and the CEL glows, this is 100% normal and is the same deal key on, no started. it only means you have power to the ECU/PCM and is basically happy (rudimentary self tests pass)
there many are reasons (0ver 50 ) to cause a stall.
but of the check light glows running and over 800rpm
800 RPM (got a dash tachometer. next time see what i does)
if the CEL glows engine running that is the warning that there are
errors. not reporting the actual DTCs here, is a big issue.
each DTC has specific cause. 335? DTC?
P0340, 355, 336
and RPM dead cranking,
the ECU will infact set DTC for CKP pulse, 1 in 10 missing
it does that and you can be sure its not fibbing.
on many cars, (on engine option (size) stated, so....????)
1.7L or 2.0L? (auto or manual tranny)
the car dies the instant you loose the CKP, the crank sensor
but not all. on dizzy cars, (distributor) it runs with a cam sensor good.
but id bet yours needs the CKP to run.
if your DTC error decodes to bad CKP then you can believe that.
this assumes you did not lose, 12vdc electr. power to the EFI system.
or the wires are damage to any ckp or cmp sensor.
again, post the DTCs?
if confused or are a real serious DIY (most arent) go to
alldata.com and look, look up your DTC and read the reasons.
they are clear.
i just looked on line, this car even has a CKP learning procedure
do not knee jerk sway any sensor, read the FSM
see the tests to be sure its bad,
see the Vref test at the sensor, if that is bad, the sensor can no work.
Engine running, and the PCM detected the Crankshaft Position (CKP
) Sensor \'A\' signal was missing for a short period of time. Note: This trouble code is usually caused by an intermittent fault. Possible Causes:
- * CKP Sensor \'A\' signal circuit is open or shorted to ground
- * CKP Sensor \'A\' signal circuit shorted to VREF or system power
- * CKP Sensor \'A\' is damaged or has failed
- * PCM has failed
try pulling it cleaning the connector and putting it back, (at the least)
alldata.com, or get a real FSM for #1 top, support. from Honda or helm.
