Hi everyone,
we have a pretty fine CRV 2001 and been driving it for 4 months now. We bought it used at about 120000miles.
However, we have troubles with the ignition. It starts up fine (100%) when the car is cold, but once warmed up, it has troubles starting up again when you shut it down.
The engine cranks, but there is no ignition spark that would start it. It takes a couple of turning the ignition and pumping the gas pedal until it starts. It feels that it gets worse the shorter the interval between shut down and start is. If you leave it for say 10 minutes quick shopping it has troubles, if you leave it for an hour or two it starts up fine.
I was thinking it might be the idle air control / the ignition coil.

However, the check engine light came on just yesterday while the problem was around for a few weeks.
There is only one error code P0118 displayed.
My app says its Engine Coolant Temperature Circuit High Input.
Reading out the computer data while the car was idling in the parking lot, the car thinks the temperature after ignition is at -18.4F, when it's been ~50F outside the whole day (southern california).
Does that also explain the long start up procedure when the car is warmed up?

What I also experienced was that the RPM was oscillating when I parked the car and was about to turn it off. (Transmission in park mode)
Happened only once though, yet.

Suggestions / thoughts / experience on that issue anyone?
Thanks,
EL

Welcome in it could be any of these problems

• A bad connection at the sensor ,An open in the ground circuit between the ECT sensor and the PCM ,A short in the voltage feed between the sensor and the PCM ,A bad PCM (less likely)
• A bad temperature sensor

I would try looking for a loose wire to the sensor,if not then replacing the sensor would be the next step.
